120 Volt and 220 Volt Electrical Circuit Wiring

Question: Would it be possible for me to safely install electrical wiring and tap into a 220 volt circuit junction box with an insulated neutral wire to provide power for a 110 volt circuit power supply.

This electrical question came from: Steve, a Homeowner from Leavenworth, Washington.

Steve, no this is not a safe practice at all, and I would encourage you to find another solution.
The particulars of the application or the existing circuit have not been provided, so I can suggest that another 120 volt circuit should be considered to see if it will provide the capacity for your specific application.

Understanding 220, 230 and 240 volt Electrical Circuits

• Most 220 volt circuits do not have or use a neutral wire, with the exception of major appliances.
• Tapping into a 220 volt major appliance circuit is not permitted because there will most likely be a amperage difference, so the tapped circuit would not have correct circuit protection which would produce a hazardous condition.
