GFCIs can trip due to a ground fault, which occurs when electricity leaks from the circuit. This can happen if water or moisture gets into outlets, there is a wiring issue, or there is a fault in an appliance. Tripping is a safety feature that cuts off electricity to prevent electric shocks and fires.

How do you wire a 120 volt gfci into a 240 volt three wire?

You can't. The 120 volt GFCI is probably just a 2-wire (hot, neutral and ground) You would have to run a new 3-wire (2 hots, neutral and ground). The two hots are how you get the 240 volts (120+120=240). Also you must make sure the wire is gauged properly. #10 wire for 30 amps, #12 wire for 20 amps, etc.


Can you put a GFCI into a circuit with an existing GFCI and what will happen if the two GFCIs are in a series circuit?

It is not recommended to install two GFCIs in series as they can interfere with each other's operation and lead to potential tripping issues. It is best to have only one GFCI per circuit for proper functionality and protection against electrical hazards.


In US or Canada are RCDs or updated GFCIs now used with 240 volt balanced household AC power mains supplies to trip on any significant difference between the currents flowing in the live and neutral?

Yes. In Canada no, the main incoming service is not protected with GFCI's. The code calls for selective branch circuits to be protected. In the new code regulations the GFCI's will be replaced with arc fault protection to monitor the selective circuits.


If an outdoor outlet gets wet will it trip the gfi breaker?

Yes, if water reaches the outlet and causes a ground fault, the GFCI (Ground Fault Circuit Interrupter) breaker will trip to protect against electric shock. It's important to keep outdoor outlets protected from water exposure to prevent this from happening.
