Electrical Tips to Help You Wire it Right

The Safest Way to Test Electrical Devices and Identify Electric Wires!

The Non-Contact Electrical Tester
This is a testing tool that I have had in my personal electrical tool pouch for years, and is the first test tool I grab to help identify electrical wiring. It is a Non-contact tester that I use to easily Detect Voltage in Cables, Cords, Circuit Breakers, Lighting Fixtures, Switches, Outlets and Wires. Simply insert the end of the tester into an outlet, lamp socket, or hold the end of the tester against the wire you wish to test. Very handy and easy to use.

The Quickest Way to Check for Faulty Electrical Wiring!

The Plug-In Outlet Tester
This is the first tool I grab to troubleshoot a problem with outlet circuit wiring. This popular tester is also used by most inspectors to test for power and check the polarity of circuit wiring.
It detects probable improper wiring conditions in standard 110-125 VAC outlets Provides 6 probable wiring conditions that are quick and easy to read for ultimate efficiency Lights indicate if wiring is correct and indicator light chart is included Tests standard 3-wire outlets UL Listed Light indicates if wiring is incorrect Very handy and easy to use.

Strip Off Wire Insulation without Nicking and Damaging the Electric Wire!

The Wire Stripper and Wire Cutter
My absolute favorite wire stripping tool that I have had in my personal electrical tool pouch for years, and this is the tool I use to safely strip electrical wires.
This handy tool has multiple uses:
The wire gauges are shown on the side of the tool so you know which slot to use for stripping insulation.
The end of the tool can be used to grip and bend wire which is handy for attaching wire onto the screw terminals of switches and outlets..

The wire stripper will work on both solid and stranded wire. This tool is Very Handy and Easy to Use.

Warning About Splicing Electrical Cables and Circuit Sizes
How is a remodel project in a garage wired where a separate room will be added?

Paul, a Homeowner in Arizona asks:

  • I am working on a remodel project in my garage where I will enclose and insulate a room from the rest of the garage.
  • I have a question about codes for splicing cables. Is this a really bad idea? I’m thinking of running a 10/2 NM cable to an electrical box, and then splicing 3, 20amp (12/2) cables from it for the little room which will pull some big electricity (music equipment).
  • I think I know the answer: it would potentially pull 60amps through a 30amp cable.
  • If so, does this mean if I want 20amp receptacles, I must use separate #12 cables?

I hope this question makes sense, and I really appreciate your time. Thanks a bunch!

Michael in South Carolina asks:

  • My garage has three switches to turn on several lights simultaneously. I just recently made a room in part of the garage and want to use one of the existing lights that are in the new room, but have it isolated on its own switch. There will also be a ceiling fan in there as well.
  • I tried running new wire from a new switch to the light but all the lights still come on and trips the breaker when the new switch is turned off.
  • There are two pairs of what looks like 14-2 at the existing light fixture. I gave 12-3 running from the new switch to the light. Thank you for your help.

Paul’s Garage Wiring Project:
Splicing Electrical Cables for a Garage Wiring Project

  • There is nothing wrong with splicing wires as long as the junction box is accessible and you are not mixing wire sizes.
  • You may not splice a #10  wire with a #12. The circuit size must be determined up front, and for your garage outlets you may want a 20 amp circuit which a 12/2 NM Romex could be installed.
  • I can tell by your questions that you really don’t understand electrical circuit design, and I’m suspecting that your project is being done without a permit.
  • Both of these deficiencies spell trouble so I would advise you to slow down and make sure the remodel project is done correctly and according to code, otherwise you’re creating a fire hazard and we sure don’t want that.

Michael’s Basement Wiring Project:

  • Consider installing a separate power source to the room in the garage that will be used for the lights and outlets.

Power from a UPS Power Supply

Electrical Project: Is it possible to wire 4 outlets together with 12-2 in 4 separate rooms and instead of the outlets receiving power from the breaker box.

How to use a UPS for a WiFi Router

Trent’s Proposed Home Wiring Project:

  • So, I was wondering if its possible to wire 4 outlets together with 12 2 in 4 separate rooms and instead of the outlets receiving power from the breaker box.
  • They receive power from a 1500watt APC battery backup ups.I have 4 orange outlets.
  • They are all daisy chained together.
    In theory what I want to do, is plug my UPS into a white outlet and then plug a male male cord from one of the backup plugs into on of the orange outlets.
    The hope is that the UPS will share power to the Orange outlets, and then when the power fails still keep anything plugged into the orange outlets up.
  • A: Will this work?
  • B: Would I need to take a ground from one of the orange outlets and ground it to another outlet?
  • C: I want my networking devices on this orange chain so WiFi router, switch, alarm clock. (way less than what my 1500w can cover)

This request came from Trent in Charleston, West Virginia.

This electrical wiring project is about wanting to share power from a UPS backup power system.

Wall Outlets and a UPS Power Supply

Trent, from what you have described, conceivably, and in theory a system like this would work – BUT I would not repurpose the existing wiring with this type of setup.

  • I would not repurpose the existing wiring with this type of setup. If this was a new home being wired then dedicated wiring for a battery backup or generator system would definitely be possible.
  • This is basically how emergency power circuits are installed and function in hospitals and other required facilities to the red or orange outlets as required – but these are isolated circuits originating from their own emergency panel, which is also isolated from the Normal Utility Power because of a transfer switch. 
  • The biggest concern that I have is using the male to male suicide cables – which are extremely dangerous, and also the possibility of back feeding the backup power back into the panel, and all of the other circuits which WILL happen with this type of set up – unless the circuit breaker for this circuit is turned off.
  • So to summarize, with this purposed setup there is no provision to prevent the back feeding of power back into the panel system, and the electric utility grid.
  • This is a great idea – but full of potential problems and hazards.
  • The safe way is to consider obtaining a few smaller UPS’s for each location where you need this type of backup power.

Problem with an Electric Heater
Electrical Furnace Problem: Why does my electric furnace trip the circuit breaker when it is turned on?

My electrical wiring project involves Tripping Breaker for a 220 Volt Electric Heater.

  • I have a Revolv Stylecrest RP7RE-048K. The air conditioning works fine. When I turn on the furnace it trips the 50 AMP circuit breaker at the back of the electric meter.
  • There is a 60 amp breaker just outside the unit that I think is being used as a switch to open the power near the unit. The unit is wired with #8 AWG wire from the switch to the unit.
  • I don’t know the AWG from the 50 amp breaker to the switch. The AC guys said the wire gauge should be #6.
  • The AC guys can’t figure out why the 50 amp breaker is tripping. The tech spec for the RPC1448 says it is 50 amp. Could the breaker be bad? The AC guys disconnected one of the heating elements and it is OK for now. Any leads would be greatly appreciated.
  • Follow Up: I should have mentioned that it takes about 10-15 minutes before the breaker trips. Maybe that is when the 2nd heater energizes?Thanks for your help. Greatly appreciate it.

This electrical wiring question came from Bill, a Homeowner in Winter Garden, Florida.

Tripping Breaker for a 220 Volt Electric Heater

This electrical wiring problem is about a Tripping Breaker for a 220 Volt Electric Heater.

220 Volt Heating Element Causing a Tripping Breaker

  1. From what has been described in this question, I would focus on the heating element that has been disconnected.
  2. The wiring to the element should be inspected for any discoloration or a faulty connection.
  3. If there is nothing wrong with the wires or where the wires connect for the element then the element is most likely at fault.
  4. It is possible that a portion of the heating element has shorted to a grounded surface of the furnace which has caused the 50 amp breaker to trip off when the furnace is turned on and is calling for heat.
  5. The power to the electric furnace should be turned off and the heating element assembly should be removed and inspected.
  6. If the heating element has any irregularity, or there are signs that an electric arc has occurred then the heating element will need to be replaced.
  7. Also, the wire size for this specific furnace should be compared to the installation manual to make sure the circuit wiring is correct.

Electrical Furnace Problem: Why does my electric furnace trip the circuit breaker when it is turned on?

My electrical wiring project involves Tripping Breaker for a 220 Volt Electric Heater.

  • I have a Revolv Stylecrest RP7RE-048K. The air conditioning works fine. When I turn on the furnace it trips the 50 AMP circuit breaker at the back of the electric meter.
  • There is a 60 amp breaker just outside the unit that I think is being used as a switch to open the power near the unit. The unit is wired with #8 AWG wire from the switch to the unit.
  • I don’t know the AWG from the 50 amp breaker to the switch. The AC guys said the wire gauge should be #6.
  • The AC guys can’t figure out why the 50 amp breaker is tripping. The tech spec for the RPC1448 says it is 50 amp. Could the breaker be bad? The AC guys disconnected one of the heating elements and it is OK for now. Any leads would be greatly appreciated.
  • Follow Up: I should have mentioned that it takes about 10-15 minutes before the breaker trips. Maybe that is when the 2nd heater energizes?Thanks for your help. Greatly appreciate it.

This electrical wiring question came from Bill, a Homeowner in Winter Garden, Florida.

Tripping Breaker for a 220 Volt Electric Heater

This electrical wiring problem is about a Tripping Breaker for a 220 Volt Electric Heater.

220 Volt Heating Element Causing a Tripping Breaker

  1. From what has been described in this question, I would focus on the heating element that has been disconnected.
  2. The wiring to the element should be inspected for any discoloration or a faulty connection.
  3. If there is nothing wrong with the wires or where the wires connect for the element then the element is most likely at fault.
  4. It is possible that a portion of the heating element has shorted to a grounded surface of the furnace which has caused the 50 amp breaker to trip off when the furnace is turned on and is calling for heat.
  5. The power to the electric furnace should be turned off and the heating element assembly should be removed and inspected.
  6. If the heating element has any irregularity, or there are signs that an electric arc has occurred then the heating element will need to be replaced.
  7. Also, the wire size for this specific furnace should be compared to the installation manual to make sure the circuit wiring is correct.

Light Fixtures that Stop Working
Electrical Project #1: I have a wall plug which I use for a table light. I attempted to turn the light on, but the light will not work.

  • I attempted to turn the light on, but the light will not work. It was working earlier in the day.
  • The bulb is good and I reset the breaker for that specific plug and still got nothing. Also I noted that two adjacent wall switches are not working either.
  • Other wall plugs and switches serviced by that breaker are working.

This electrical wiring question came from: Glen, a Homeowner from San Antonio, Texas.

Electrical Project #2:

  • We have 2 ceiling fan/light combos. One in the den and one in the kitchen.
  • The other day the light in the den cut off.
  • When I flipped the switch it did not come on.
  • There was the same exact issue in the kitchen.
  • All other lights and appliances work perfectly.
  • I checked the circuit breaker outside and nothing was tripped.
  • I checked the fuse box and noticed that out of the 4 fuses (3 15amp SL & 1 20amp D), one of the 15 amp SLs was broken.
  • I replaced it and when I did, the new one ‘popped’.
  • Also, our house alarm had a trouble light come on and we were contacted by our security company. They said the battery was low or dead.
  • We replaced the battery but we still have the trouble light, and both above items still do not work.
  • The house is 65 years old.

Light Fixture Electrical Circuit Problems

electrical project checklist

  1. Light Switch and Electric Wiring
    • Glen, because you have stated that the electrical power is not working for more devices in this room the wall light switch should be tested. The wire splices located in the wall switch electrical box should be examined for possible loose or burnt connections.
  2. Identify a Problem Wire Splice
    • In many cases such as this the problem may be caused by a faulty electrical connection or an electrical splice connection that has failed.
  3. Checking Other Switch Locations
    • All electrical junction boxes associated with this circuit should be opened and examined as well until the problem has been located.
  4. Repairing an Electrical Wire Splice
    • Burnt wiring or electrical wire splices will need to be repaired by removing the burnt areas of the wire and creating a new splice with a quality wire connector.
    • It is best to use a pair of pliers to twist the wires together gently and then trimming off the ends of the wire.
