If you reverse the line and load light switch, the GFCI cannot trip in the event of a ground fault. The ‘RESET’ button will pop out if you test the receptacle by pressing ‘TEST.’ However, the GFCI will retain power.

What happens if you wire a light switch backwards?
A light switch has no polarization so when you reverse the connections on the light switch it works just as before you reversed the wires. Originally Answered: What happens if you wire a light switch backwards? Normal switches only have two poles and cannot be wired backwards. The black wire is the hot wire and a black wires go on each pole.
What happens if you bypass a light switch?
A light switch only interrupts the hot side and the neutral wire bypasses the switch. Amateurs will sometimes reverse this. The result is that the light will appear to work normally (making the error hard to detect). But what that means is the light is ALWAYS energized and only the return at the switch is toggled on or off.
Can you put an LED light switch in the neutral?
Light switches have no forward or backward; only on and off. They must be installed in the hot line and not the neutral. If you install them in the neutral, the fixture will work, but will be hot all the time, which is not good if you happen to need to work on it or accidently touch the shell of a lightbulb that you are installing.
What happens if you put a white wire on a switch?
The white wire is the neutral and is grounded in the breaker box and runs to the load and not through the switch. If you put a white wire and a black wire on the switch poles the best case is that you get a dead short and you trip the breaker. The worst case is the switch explodes and creates a fire.
What happens if you switch line and load on a light switch?
You could put the switch on the neutral wire and everything would work, but it would leave voltage potential to ground in the light when it is switched off. That makes it a bit hazardous for changing light bulbs. If you became an electrical path to ground through a wet floor or something you could get a shock.
What happens if you reverse wires on light switch?
A light switch is a simple device with only two states, competing a circuit (On) or breaking a circuit (Off). It is a series control element is a series - parallel circuit design. A light switch has no polarization so when you reverse the connections on the light switch it works just as before you reversed the wires.
Does line and load matter on switch?
Common Terminal: When installing a Brilliant, the Common wire hole is where you will insert your “Line” or “Load” wire into the Brilliant base. Brilliant can automatically detect which wire is “Line” and which is “Load”, so it doesn't matter which of these two wires you install into the Common wire hole.
What happens if I hook up a light fixture backwards?
If wired correctly, there will be no power to the fixture unless the switch is on. If wired backwards, there will be voltage (but no current) to the fixture, until the switch is on. Normally this won't matter, unless there is something wrong with the fixture….
Can Reverse polarity cause a fire?
Yes, if you accidentally reverse the polarity on an electrical outlet, the device you plug in to the receptacle isn't safe and could cause a short circuit, shock, or fire.
What happens if you connect wires backwards?
But here's the catch: If you connect the circuit wires to the wrong terminals on an outlet, the outlet will still work but the polarity will be backward. When this happens, a lamp, for example, will have its bulb socket sleeve energized rather than the little tab inside the socket.08-Jun-2021
Can wiring a light switch wrong cause a fire?
A short circuit can cause the breaker or fuse to pop. If the fuse does not burn out, the wires in the device may melt. This would damage the smart switch, most probably irreparably. If the wires in the circuit became hot enough, the resulting resistance could even cause a fire.
Does line and load matter on single pole switch?
If you are speaking of a single pole switch, doesn't matter. On a 2 pole switch, box mounted, technically it doesn't matter, but good practices are line at the top, load at the bottom. If a disconnect switch, always line at the top, load at the bottom.
What happens if you mix up line and load on GFCI?
If you mistakenly connect the LINE wires to the LOAD terminals, the GFCI will not reset and will not provide power to either the GFCI receptacle face or any receptacles fed from the GFCI.
What happens if you reverse hot and neutral wires on a light fixture?
When an outlet is wired in reverse, the hot wire is now on the supposed neutral side. So, if you were to plug in the same lamp as noted above, the lamp socket would have power even if the switch was off since the switch is only on the hot side.08-Dec-2020
What happens if you mix up black and white wires?
It will produce a big spark and hopefully blow a fuse or trip a breaker. If you wire them together and then turn the power on, the spark will occur at the breaker or fuse. Either way, don't do it.
Does it matter if live and neutral are reversed?
There are no polarities in AC, so live and neutral can get interchanged without any problem in AC circuit in appliances. However, when it comes to wiring in house, live and neutral should not be interchanged.
What happens if you wire an outlet backwards?
Will an outlet work if wired backwards? But here's the catch: If you connect the circuit wires to the wrong terminals on an outlet, the outlet will still work but the polarity will be backward. Inside an outlet's electrical box, the black (hot) wire should be connected to the brass-colored terminal on the outlet.
What is the difference between a load and a line?
Line is the side of the device where the wires from the panel (or other equipment feeding the device) are connected. Load is where any devices that are to be protected by the GFCI device are connected. Most "newer" GFCI devices will not reset if they are not connected probably. Correspondingly, what happens if you reverse line and load light switch?
Does GFCI work with reverse polarity?
Accordingly, will GFCI work with reverse polarity? Since testers establish a test circuit between hot and equipment ground, if the receptacle into which the tester is plugged is wired with reverse polarity, there will not be a voltage across the tester and test current will not flow.
