GFCI Circuit Breaker and Wiring
How to Wire a GFCI Circuit Breaker: Does it matter where in the breaker box panel I insert a 20 amp GFCI 220Volt breaker?
GFCI Circuit Protection Requires Correct Circuit Wiring
- I moved some breakers around and put the GFCI breaker above, closer to the main breaker, a single pole breaker that feeds some outlets.
- Now whenever I plug in a tool with a motor in it and turn it on the GFCI breaker trips and irrigation pump shuts down.
- Do the GFCI breakers need to be last in line in the panel, furthest away from the main breaker ?
- Or should I use a regular breaker in the panel and move the GFCI breaker to the end of the feeder line next to the pump. Or should I be doing or not doing something else.
Thanks for your help,

How to Wire a GFCI Circuit
- The location of the GFCI circuit breaker does not affect the operation.
- I’m curious – what are you providing power for that requires a GFCI Circuit breaker, and – if this device actually requires GFCI protection, have you installed all the necessary wiring?
- For example, most spas and hot tubs require a 4-wire GFCI circuit where a separate neutral wire is required.
- If you are providing 240 volt power to an agricultural pump that does not require GFCI protection or a separate neutral then you just need to install a regular 2-pole 240 volt circuit breaker.
- Make sure to install the wiring as required for the specific motor size and a properly sized and bonded ground wire.
