There is more to it that just the bulbs. You have blown all the chokes/ballasts that supply the power to the tubes. Nothing is going to survive twice the recommended voltage.I found this from an old Fixya posting.

You probably have T8 ballasts controlling your lights which are electronic. Its pretty much a sure bet that these are fried and will need to be replaced. Open up the tray that is between the bulbs and write down the F32T8x? Number that is on the front of the ballast. The ? Will be the number of bulbs it is designed to run. As long as the number matches up you can just cut the old ballast out and it wire the new one in. Ballasts generally run ~ $20 a piece. Hope this helps!

Stand up tanner requires a 240v 20amp receptacle and power supply, it was working at my last place I have the same receptacle and breaker however, I didn't pull the wire I bought 10/3 wire HELP PLEASE


If you need 240 volts only, it should work. If the tanner uses both 120/240, (which I would expect), you will need 10/3 with ground (it appears in the jpeg that you are using 10/2 with ground).

For 240 volts, 10/2 has two conductors,. Measuring with a voltmeter between each leg you get 240 volts. With 10/3 the third conductor is a neutral (there is no neutral in a 120 volt circuit). This carries the unbalanced load between the two legs and allows the appliance to use 120 volts as well. The conductor coloring is usually black, red for the power legs and a white grounded conductor (with a bare, grounding conductor).

If the cord has four pins , it needs 10/3 with ground. If it has three pins (240 volt only) the recept is probably wired wrong.

Ion tailgater speaker - changed the ac switch from 240 to 120 and now it wont work? Live in uk if it helps


Hi
The fact that you live in the UK is key to this. The mains voltage in the UK is normally 220 - 240 volts and your system should be set to 240 volts. If you changed the voltage switch to 120 volts and then tried to use it, you will have connected circuitry within the box designed for 120 volts to 240 volts. This will have damaged some of the circuitry for sure.
Your best bet is to return the ac switch to 240 volts and hope that the 120 volt and 240 volt sets of circuitry are completely isolated from each other within the box, so that resetting the ac switch will allow the kit to work.
I strongly suspect that the kit will need to be professionally repaired, and will be useless until it is.
Not perhaps the answer you would have preferred but hopefully of some help, if so would you please register that with Fixya
Cheers

How do I wire GE# 15351 24hr mechanical timer switch for 110 volt outdoor landscape lights


15351 is 240 Volt timer... requires 240 Volt to run clock motor.
You need a neutral wire to connect 120 Volt lights.

15351 has same wiring as Tork 1104

I live in germany (military) what is the power 120-240?


Good day!! The 120-240 power simply means the supply of your TV can be plug in to 120 Volts AC to 240 Volts AC that will come out to your outlet.For example your outlet is 120 Volts AC you can plug in your TV in there.In short your TV supply is auto-volt.
I hope this information could help you.Thank you.

How do I know if my Hotpoint oven 920 years old0 is on a 220 0r 120 line? The serial plate says 120/220.


An oven uses both 120 & 220 -- actually it would be 120 volts and 240 volts or nominally, 110 volt and 220 volt.

The 120 is used for the lights. The 240 is used for the heating elements.

A 240 volt breaker (nominally 220 volt) -- supplies both 120 and 240 volts depending on how the supply is connected to the appliance.

There will be a 240 volt (nominally 220 volt) breaker in the main panel for the oven. This is two 120 volt breakers side-by-side with their toggle switches connected together with a strap across the top of the toggles.

How does one wire the T104. Can the T104 be wired via a 120 volt, 20 Amp Breaker Supply


No, the Intermatic T104 requires 240 volts for the clock motor.

The T103 has a 120 volt clock motor and will control a 240 volt load, but requires a 3-wire (with ground) supply cable [as opposed to only a required 2-wire (with ground) for the T104].

The T101 uses a 120 volt clock motor and controls 120 volt loads.

T103 clock not working


Please read all of this post. You may burn up the 120 volt T103 timer motor is you are not careful.

The statement: "I have 120v board with 120 constant and 240 timed" is not very clear to me as to what you mean.

In US residential wiring, the white wire is not always the "neutral;" The white wire is sometimes used for 240 volt circuits.

We cannot tell you how to wire your timer unless we know _exactly_ what you have.

If your incoming supply cable (from the breaker box) has 3 wires (black, white, and bare), there are two scenarios:

1...If the voltage from black (hot) to white (ALSO hot in this case) is 240 volts, and you have only 3 wires (black, white, and bare), then the T103 is the _wrong_ timer if you are trying to control a 240 volt load. You should use a T104 timer.

The T104 uses a 240 volt timer motor and the T103 uses a 120 volt timer motor.

2...If the voltage between black and white is 120 volts, then you will only be able to control 120 volt loads; then the incoming black supply wire is connected to terminal 3 and the white (neutral) wire is connected to the "A" terminal. The bare equipment grounding wire is then connected to the "GR" terminal.

To show the difference, if you are trying to control a 240 volt load, to use a T103 and wire it _correctly_, you would need to have a incoming supply cable with a total of 4 wires (black, red, white (neutral), and bare) Black to red would be 240 volts. Black to white would be 120 volts. Red to white would be 120 volts.
The connections would be as follows:
White (neutral in this case) to the "A" terminal
Black to terminal 1
Red to terminal 3
The 240 volt load would then connect to terminals 2 and 4
Both the bare equipment grounding wires are connected to the "GR" terminal.

Since you did not mention a red wire, I can only ASSUME that this is not the case.

Sorry, we can't tell you how to wire this timer based upon assumptions.

So, what do you have?

BOSE DOESNT TURN ON AFTER PLUGGING TO A 220-240V PLUG AND ITS ONLY 120 VOLTS


It sounds like you hav blown a fuse. Hopefully just a fuse, connecting a 110 to a 240 will hurt.
Most equipment survives short term high voltage but sometimes it just can't take it.
if it's not the fuse then it's very likely damaged the power supply which will require the expert help of a technician..
good luck !
Ps the 321 is a very nice bit of kit..
