== == == == It's a receptacle symbol, usually with "GFCI", "G", or "GFI" written under it. To find out exactly which symbol is used on your prints, look at the electrical legend, which is normally page E-1, E-001, etc.
The terminology down stream refers to an electrical circuit and where devices are connected into the circuit. In reference to the breaker that feeds the circuit everything is down stream from it. If a GFCI receptacle is added into the circuit as the first device, the GFCI can be wired to allow all of the regular receptacles to be protected down stream from that GFCI. Every device added to the circuit will be down stream from the one that is ahead of it. The only device that will not have something down stream from it will be the last device in the circuit.
Yes but it's redundant and may cause unnecessary "tripping" of the circuit. The GFCI circuit breaker is intended to protect an entire receptacle circuit whereas a GFCI receptacle is designed to protect only that receptacle and any which are provided power from its load side. (downstream)
Yes. GFCI receptacles do not rely on a ground conductor to work. They sense any difference between current flowing in the hot wire and current returning in the neutral wire. Under normal circumstances, these two currents will be exactly the same. If there is a difference, then some of the current is flowing from the hot to somewhere else, possibly through a person to ground. This causes the GFCI to trip. The National Electric code even permits an old 2-wire receptacle with no ground wire to be replaced with a GFCI 3-prong receptacle. No ground wire is used, and the GFCI must be labeled "No Equipment Ground". See NEC Article 406.3(D)(3)(b) and (c). This is the only legal way to install a 3-prong receptacle in place of a 2-prong without running a new ground wire.
electrical symbol
I have never come across a symbol for an electrical resistance box. As the resistance box is a test instrument and it would not be drawn on any electrical schematic there may not be a symbol designated for it. The last letter of the Greek alphabet is (Ω omega) and it is used for the electrical symbol for resistance.
A down stream receptacle that is connected to the upstream GFCI will be protected. If the downstream receptacle senses a fault the upstream GFCI will trip.
Your GFCI receptacle may not be working due to a tripped circuit, a faulty GFCI receptacle, or a wiring issue. It is important to troubleshoot and potentially replace the receptacle to ensure safety and functionality.
When installing a GFCI receptacle outdoors, it is important to consider safety measures such as ensuring the receptacle is weatherproof and protected from moisture, using a weatherproof cover, and following proper installation guidelines to prevent electrical hazards.
Yes, there is no reason why this can not be done. In fact a benefit of this is that every receptacle downstream from this new receptacle will also be protected by the GFCI receptacle.
Most probably the receptacles downstream from the GFCI would not be protected by the GFCI receptacle.
Not if the GFCI breaker is supplying the circuit you are wanting to put the GFCI receptacle into.
To wire a GFCI receptacle, first turn off the power to the circuit. Then, connect the black wire to the brass screw, the white wire to the silver screw, and the bare copper wire to the green screw. Finally, push the wires and receptacle back into the electrical box and secure it in place.
Actually, yes. The GFCI does not need any ground; it measures "leakage", i.e., an imbalance, regardless of whether there is "ground". The National Electrical Code permits installing a GFCI to replace a completely ungrounded receptacle. Others have said: No. The GFCI is designed to measure an unintended path to ground. Without a good ground reference this is not possible.
Yes, an electrical switch can be installed before a GFCI outlet in a circuit. Just ensure that the wiring is done correctly, following all safety guidelines and local electrical codes. The GFCI outlet should be properly connected to the power source and the switch should be wired to control the flow of electricity to the outlet.
8 ozs. and will vary by mfr. for an in-wall receptacle.
When installing an outdoor GFCI receptacle, it is important to consider the following safety precautions: Ensure the receptacle is weatherproof and rated for outdoor use. Install the GFCI receptacle at least 12 inches above the ground to prevent water damage. Turn off the power supply before installation to avoid electrical shock. Use a waterproof sealant or cover to protect the receptacle from moisture. Follow the manufacturer's instructions carefully to ensure proper installation and functionality.
Yes.
