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?
Note: The latest types of Ground Fault Circuit Interruptor (GFCI) are also called Residual Current Devices (RCDs)."Can you put a GFCI into a circuit with a GFCI?" is probably the same question as "What if two GFCI are in series in a circuit?" and the answer is that one GFCI will most likely trip earlier than the other to break the circuit. Which one will trip first depends on the actual difference in sensitivity between the two GFCIs. Leakage currents are measured in mA (1 mA = 1 thousandth of an Ampere) and GFCIs are designed to trip at a certain leakage current with a tolerance of say + or - 3%. So if the basic trip current was 20 milliamps one GFCI might trip at 19.4 mA and the other at 20.6 mA and they would both be within the design specification. The one that trips at 19.4 mA would be expected to trip first. This question requires answering by a VERY knowledgeable electrician, or an electrical engineer. I am neither, but until the right answer comes along, I will attempt to provide some information which hopefully will allow a better understanding of the issues involved. A GFCI [ground fault circuit interrupter] is much different from, although similar to, a circuit breaker. The DIFFERENCE is WHAT they are designed to detect and react to. The purpose of a fuse or circuit breaker is to detect excess or MASSIVE current flow [ie. a SHORT CIRCUIT, a direct short to ground], and then very quickly turn off the electrical current to the circuit, in order TO PREVENT a FIRE. This is the only thing the breaker is designed and intended to do. This limited capability will not prevent a person from being electrocuted when a fault occurs within an electrical device, if the current flow happens to be low. Voltage and current faults which can kill a person usually will not be detected by a circuit breaker. A ground fault circuit interrupter [GFCI], on the other hand, is designed to, and will, detect those low level currents which can kill a person, BUT which are not great enough to trip a breaker. When a GFCI detects potentially dangerous current it, like a breaker, trips in order to open the circuit. Now as to WHY, when you placed two GFCIs in series [one in the breaker panel feeding one in an electrical receptacle], the first GFCI tripped when the second GFCI is "tested." When you press the TEST BUTTON on a GFCI it puts a high resistance load on the circuit, which simulates a "small" ground fault, and I think both GFCIs "see" the same fault and react as designed and intended. Again, a true professional should "bless" my comments, but I think that there is no danger or hazard in placing two GFCIs in series. On the contrary, I think there is redundant capability in the pairing, with the first GFCI functioning with, and as a backup to, the second. I suggest you contact your local electrial inspection department regarding what the code(s) say about this issue, and also call the tech support people at the 800 number on the packaging for the GFCIs. Another source of information is a local electrical engineer, if you know someone who can help you make contact. Until a more informed answer comes along, I hope this helps you to understand the issues involved. As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.Before you do any work yourself,on electrical circuits, equipment or appliances,always use a test meter to ensure the circuit is, in fact, de-energized.IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.
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?
Answer If it doesn't trip, then the logic sensor is bad and the whole thing needs to be replaced. A residential grade gfi is about five bucks and is relatively easy to replace. Turn the power off first. This failure was common with older style GFCIs that could be surge damaged and then fail to protect human life. Newer designs will (should) not reset if a GFCI has been damaged.
When was Trip Magnet created?
Trip Magnet was created in 2010.
Do GFI's go bad over time?
Yes, Ground Fault Circuit Interrupters (GFCIs) can go bad over time due to wear and tear, exposure to moisture, or electrical surges. It is recommended to test GFCIs regularly and replace them if they are not functioning properly.

What happens to voltage during a short to ground?
Basically, the same as if you had a short to neutral, since the neutral and ground are tied to the same bus bar in the breaker panel. The breaker should trip, or the fuse should blow. Supply of voltage then stops.See the answer to the Related Question about GFCIs - shown below - for information about circuit protection when even a small current flows to ground.
GFCI circuitry checks for what?
Current Imbalance: GFCIs continuously monitor the current flowing in the "hot" (live) wire and compare it to the current returning in the "neutral" wire. If there is a difference of as little as 4-6 milliamperes (mA) between these currents, indicating that some current is not returning through the normal circuit path, the GFCI will trip and disconnect the power. Leakage to Ground: GFCIs are designed to detect any unintended flow of electricity to ground, which could be potentially hazardous. This can occur when there's a fault in an electrical device, damaged wiring, or when someone comes into contact with a live wire or conducts electricity to the ground. Rapid Response: GFCIs are engineered to respond quickly, typically tripping within milliseconds when they detect a ground fault. This rapid response helps prevent electric shocks and electrical fires.
