Assuming that your electrician is in fact qualified, he should have tested the switches after completing the work. Some people get in a hurry and overlook this important practice.

If the 3-way switches (there is no such thing as a "2-way" switch) were working correctly after being moved, then one of your switches is bad.

Don't mess around with this yourself, this is how many homeowners get hurt (or killed). Call your electrician back.

This switch system is not wired correctly which makes me wonder if the "qualified" electrician is actually qualified. Since the system is not working properly, I would first request that the original electrician comeback to fix it at no charge to you. Failing that, get another to trace the problem and fix it. I would get this fixed ASAP as there is the possibility of short circuits and fire if not addressed.

T104r timer manual switch not working, clock runs fine, on and off trippers work


The contacts inside the time clock have most likely warn out. If it is coming on randomly it is not making good contact and will create arcing, which is dangerous. Call an electrician, they may be able to replace just the internals.

How many wires are allowed to be connected on it I see 2 exra ones not in the pole


It sounds as though you are talking about a two way wall switch.

This should have three wires connected to it. A red one to the L terminal and one to L1 terminal and another to L2 terminal. If you are not sure what type of switch it is or what you are doing, consult a qualified electrician. Electricity kills!

I want to install a light in my garage i have a live source but how do i connect it to the light and wall switch


My first response would be to seek help from an electrician or someone qualified to perform this work.
If you are going to attempt it, you will need the following items:
- electrical box
- light switch
- light fixture
- wire ( ask you local hardware store clerk what is recommended or needed to meet code in your area.

Disconnect power at breaker to your source.
From your source,
- connect wires to electrical box. then to;
- connect wires to switch then to;
- connect wires to another box at the fixture
- connect fixture to the box.

How do I wire for 2 seperat lights on a commom system?


{SW1}---Light 1 switched leg to fixture 1
HOT wire (Line or Feed)----{
{SW2}---Light 2 switched leg to fixture 2

The wire supplying power to the switches will be connected to the "LINE" terminals tied together with a breakaway tab (common feed). The upper "LOAD" side terminal will output to the first light and the lower "LOAD" side terminal will output to the second light. The neutral (White) wires if present will be joined together (wirenut).

All electrical work should only be done by qualified individuals.

Shower short circuits downstairs wall sockets when turned on


Turn the circuit breaker to off and don't try to use it. Something has shorted this circuit out, whether a wire came loose or what. It is very difficult to diagnose without more information, ie, what is it wired to, is it new or recently installed and just stopped working, or has it not ever worked?

But it is extremely dangerous in its current state and you could even be electrocuted. I recommend that you call the original installer, or a qualified electrician to come out and have a look at it. They will have the proper equipment to diagnose it and repair or replace it.

My tenant was complaining taht he was getting a shock when he touched a Leviton 104-05611-2WS 15A Decora Single Pole switch for a bedroom closet. My problem is I now cannot figure out how to reconnect the...


The three black wire are as follows: One is the hot wire. One feeds the closet light. One feeds the lights for the kithen and bath. Turn off the power at the circuit breaker or fuse panel and disconnect all three black wires and be sure they aren't touching anything. Turn the power back on and using a test light or meter determine which black wire is live. Turn the power back off and mark the hot wire with a pen, marker, or piece of electrical tape. Connect the wire you marked with a wire nut to one of the other two black wires. Turn the power back on. If the closet light comes on, that is the wire that you want to connect to one of the terminals of the switch. If the lights in the kitchen and bath now work, leave these wires connected together and connect the third wire to one of the switch terminals. Turn the power back off. While the hot wire and the wire for the kitchen might have both connected to the switch terminal, this is no longer allowed by code. Instead take another piece of wire of the same type and connect it to the hot wire and the kitchen wire with the wire nut and connect the other end to the other switch terminal. There should be a green ground screw terminal attached to the metal frame of the switch. Using a green or bare copper wire connect this to the ground wires in the switch box. Reinstall the switch and turn the power back on. Everything should be good now. If the fuse blows or the breaker trips, replace the switch.

Bathroom Pull switch


There are two possibilities here,

1. it is a mechanical failure i.e a part of the linkage has broken leaving the switch in the on position, did you see anything obviously wrong with the old switch?

2. It is an electrical failure either overload or arcing when the switch is being operated sometimes welding the contacts together. This can happen if the light is a fluorescent tube or ring type, which in combination with the fan start up, can cause this situation. If this is the case you need a higher current rated switch.

Please remember to rate this solution.

Two way light


FIrst of all, it is actually called a 3-way switch system. I would suggest that you either consult and elexctrician or look up the Time-Life series on home projects which contains a couple of volumes on electrical projects. Included in there are complete diagrams of how to hook up 3-way switch systems.
