We just moved into a new house, and whenever I use

It sounds like it could be one of the following issues:

1. Bad wiring to the bathroom receptacle - this should be a GFCI outlet.

2. There is an overload somewhere on the same circuit - try the dryer with nothing else turned on.

3. The hair dryer may be bad or have a bad cord, plug, etc. Hair dryers can also become plugged (the air inlet screen) and overheat.

4. There could be loose or other bad wiring somewhere in the circuit.

If you are not familiar with working with electricity, it would be best to call a qualified electrician. They are the pros and can correct the problem.

How to wire up an E40 ceramic lamp holder for use with compact flurescent (sic) or high intensity discharge lights? (GENERAL ELECTRICAL KNOWLDEGE) Lights are used in factory High & Low Bay lighting;...

If this is being used as a socket for a 120-volt lamp (such as a compact fluorescent with self-contained ballast or an incandescent lamp), you wire the black (hot) AC line conductor to the brass-colored screw and the white (neutral) conductor to the silver-colored screw. If the socket is equipped with pigtails instead of screws, use pressure connectors (wirenuts) to connect black to black, white to white.

If you are using HID lamps, you don't wire directly to the AC line. These lamps must be used in a fixture with the correct ballast transformer, capacitor and ignitor (for pulse-start lamps) for the lamp wattage. If you are replacing the socket in such a fixture, follow the wiring of the old one when installing the new socket.

Harman P68 pellet stove glass fuse blows after 1 minute.

You can do some troubleshooting by looking at the glass fuse after it has failed. If the element looks melted and there is no other discoloration, then the fuse probably blew as a result of an overload somewhere. If the fuse is burned black, then it's probably a short in the system.

You can meter the motors to see if they are shorted anywhere or open.

It sounds like you may be correct about the circuit board.

I have wired a new light fitting into our downstairs toilet however when I came to test it the light worked but half the other downstairs lights are now switched off when the toilet light is swithced off....

Probably put your family at risk of electricution . By connecting the live cables to earth you have effectivly made all the metal light fittings live. It is amazing that the fuse has not blown, This in itself is dangerous and you should have an electrician look at the wiring.
The correct wiring should be as follows.
Identify cables there should be 2 twin and earth (red black & copper earth) cables and 1 twin red and copper earth. (or 2 single red wires)
connect all copper earth wires suitably sheathed in green/yellow sleeving to earth lug.
Connect 2 black cables to neutral block.
Connect either single red (0r 1 of 2 reds) into live block.
connect remaining 3 reds into loop block.

Do i need a special switch to run an exhaust fan/light simultaneously?

No, you can pigtail the fan and light together with a wire nut and another piece of wire and connect that to the top of a single pole switch. Connect the Common (hot) wire to the bottom of the switch, and the light and fan will operate at the same time. Just make sure the total Amps of the lighting and the fan doesn't exceed the rating of the switch.

Be sure to disconnect the power to the circuit before making any connections and if you have a metal switch box, wrap around the switch, covering the connection screws with 2-3 complete wraps of electrical tape to prevent accidental shorting against the metal box.

If you want to have the ability to run the fan and light separately, you can get a over/under switch that will fit into the single gang box. That will let you turn on either the light or the fan, or both at once.

If you have any specific issues concerning your particular installation, please use the comment box to post more info or follow up questions and I'll get back to you.

Hope you find this Very Helpful and best regards!

Home electrical problem: Lights on one circuit do not work. They were flickering for a while, then went off completely. I replaced the circuit breaker in the panel, and tightened up all the ground wir

Sounds like a bad connection. First thing is to check any wiring that you had installed or changed.

Is the home wiring copper or aluminum?

If you know that the circuit breaker is working (check with volt meter) then you have to check all the splices on that circuit. The bad splice will be the first light on the circuit

Replacing blower motor in furnace w/Fasco brand #D727

Some one missed the wiring diagram. I believe its like this:
L1 = Line 1 = (Hot all are same thing)
Black Hi
Blue Med
Red LO
Now usually the black is for AC and connects to a normally Open (NO) contact on the blower relay.
The heater speed (either red or blue) go the the normally Closed (NC) on the blower relay and on one side of this wire or contact on the relay it goes to the heating blower thermostat on the furnace.
The remaining wire (blue or red) you tape off.
L1 also feeds the Run Capacitor on 1 side and the Brown wire feeds the opposite side

The white wire is Neutral and goes to the neutral on the main line.

If this helps you please rate me accordingly and good luck.
