Can you mix two hot wires and neutral in same shut-off switch?

Yes two "hot" wires and a neutral can enter into a switch box. This is done on occasions where a three wire enters a switch box, drops off one circuit for the lighting and the other "hot" wire carries on to feed a receptacle circuit.


What is a floating neutral wire?

Why black wire and white wire both have power?

In the US, house wire has the BLACK wire connected to the HOT phase of the service input. The WHITE wire is connected to the NEUTRAL of the service input. Normally, both BLACK and WHITE wires are each connected to the 2 LOAD terminals. It is also normal that the WHITE service wire is connected to the wider spade outlet receptacle. The BLACK wire would then be connected to the shorter or narrower outlet spade receptacle. In wired screw lamp circuits, it is normal to wire the BLACK service wire to the center pad of the lamp socket and the WHITE wire to the screw shell of the socket. In switch circuits, it is normal to wire the BLACK service wire to the switch. The HOT service circuit is then opened or closed by the switch. Measuring voltage on your neutral means there is a break in neutral. If the neutral is broken you will measure voltage across the break or from the break to ground. Under this scenario you will measure the same voltage as you do on your hot wire and your load should not be working. Measuring voltage on your neutral less than on your hot wire may mean you have a problem where your neutral is supposed to be bonded to ground in your main service panel. In this scenario your load may be working but you need to check the bonding connection.

Why is it always connected in the phase or line wire to the switch and not the neutral wire?

because its much safer to switch the hot wire then the neutral wire because if you are working on a light fixture for example and the switch is off if you ground yourself out to the neutral you become the load or return. a neutral shock can me more dangerous at times

You should never switch the neutral wire. The neutral of the appliance should be connected directly to the neutral wire leading to the service panel neutral bar.

I have Two black wires and one red wire conected to a switch. Which is hot and which is neutral?

It sounds like your switch is a three way switch. The wire that is on the different colour screw of the three screws will either be the "hot" wire or the wire to the load. The neutral might or might not be in the box that the switch is in depending on which end of the three way system you are at. See discuss question button below.No wires connected to a switch are neutral. A switch breaks the circuit of the hot wire. Black AND red are hot wires. White is used for neutral and is almost never connected to a switch.


Is the white wire in the thermotat a neutral?

the thermostat has a black(line) wire to it, and a red wire going to it. the red wire then connects to the neutral wire. the black and red are like a leg switch.
