How many 3watt bulbs can be run off a 500va transformer?
To answer this question the voltage of the bulbs is needed.
Can GFCI circuit breaker handle a 240V circuit with a 120V circuit sub-paneled off if it?
I don't know if you are trying to ask if you can run a 240V panel off a GFCI or run a 120 V sub panel off of a GFCI. Can you clarify please,,,Thanks
What is the difference between 12V 7AH Battery and 12V 12AH Battery?
Both are giving the data about storage capacity of a battery. For Ex. 12V 7AH Battery will run 7 hours if you are driving the load of 1Amp continuously. But 12 12AH Battery will run 12 hours if you are driving the load of 1Amp continuously.
Can a 240V wire be run from the junction box and not the service box?
Junction box for what? Do you mean a sub panel?
How long will a 12v 2.5ah battery run a 3w LED?
12w at 12v = 1amp 3/12=0.25 0.25amp = 250ma 2.5ah= 2.5amps per hour 2.5/0.25=10 A 3w led at 12v 2.5ah battery will last 10 hours.
Can you run a 12 volt vw beetle with a 6 volt generator?
No. The ignition needs 12v to run, the starter needs 12v to crank, the bulbs all need 12v to get bright enough...
How many 12V 50W bulbs can you run on a 20-60VA transformer?
A 60VA transformer can run only one 50W bulb.
What would cause light sockets to read 130V in a 240V system when the light switch is off?
More than likely, your 240V system has branches that supply a standard household 120V to things like lighting outlets. Most light bulbs in the US run on 120V so this is probably a convenience feature. Otherwise you would have to go to a specialty store and buy 240V bulbs.
Can you splice a car stereo into a wall outlet?
No. Car stereos run on 12v DC power. A wall outlet, depending on where in the world you are, gives out either 110-120 or 220-240v AC power.
Can 240V washer run on 120V outlet?
No.
Will a 12v lithium battery rated at 1000ma run a 12v 100w light bulb?
no
Can a 12v 550ma device be run by a 12v 210ma supply?
No, the supplies output is too small. To run a 550mA device a supply source of 600mA and larger would be needed.
Will a 240v 3 phase welder run better than 240v 1 phase?
Yes, because you will be able to maintain current flow between phases.
Will a diode work as a light dimmer when switched or added in series to an incandescent 120 volt AC bulb?
Actually, I have seen this in a respected electronics magazine (Elektor) quite some time ago: A diode (selected to be capable to handle the amps, the voltage and the heat from the bulb - if placed inside the lighting fixture) is used to "cut off" one half of the AC sine wave and thus sending pulses of 120V to an incandescent light bulb, simulating a simple dimming device. The proposal was meant to run 240V bulbs at 50% of their brightness but I am pretty certain this concept can be used to run 120V bulbs from 240V power. One other way of connecting 120V bulbs to 240V would be to connect two 120V bulbs OF THE SAME WATTAGE in SERIES, so the two bulbs form their own voltage divider. Not sure what happens if one bulb burns out - I would expect the other one to blow too, as a dying light bulb represents zero Ohms (plasma/arcing) for a few milliseconds before it goes dark forever.

12 volt boat winch and you want to hook it to mains 240volt or is it easier just to run it off a battery?
You can hook up a battery and 240v 12v heavy duty charger system,that is the easiest way to get over that problem. The charger has to deliver enough amperage to cover the load from the winch.RegardsJohn Cas
Can you run two laundry dryers on one 220 circuit?
No you can only have one dryer on a 240v circuit and nothing else can be attached to it either considering your using a 240v electric dryer
