I live in an older house We have fuses instead of breakers now my question is i have a dryer plug and a stove both going to the same fuse & both are 240 the dryer plug doesnt get used What would happen if i were to A-buy a 240v extensin cord and hard wire it to fusebox where dryer is and use power else where would i run into problems? B- buy more 240 and just extend the existing wire? Now my biggest issue is them both being on same fuse is this gonna be a problem?

 

Both the stove and dryer should be dedicated circuits. They should not have been combined at the fuse panel.

Neither of those appliances should be used with extension cords.

I do not understand what you mean about buying more 240.

 

The 240 that goes from panel to plug is like a foot i need about 15-20 ft

 

And the 240 im taking wont be used fully im running it through a ballast And lowering power.. im not using a dryer im just using the power from that plug

 

That isn't what a ballast does. Do you mean using a transformer to reduce voltage not power? Each post your posts make less sense. Please explain fully what you are trying to do so we can help you.

 

Its for my horticulture shop im trying a few new exotic plants and they need certain stuff..i just need to have power for my 400watt bulb just one for now. Thats where my ballast comes in because i cant use 240 on a single 400 watt bulb. And yeah as you can tell im not a electrician haha

 

What kind of bulb?

.

 

Im on my way to work so i dont have Access To it right now.. if this helps its just 400watts and its about 10inches long and iTs about 3 inches around so fairly thin

 

Its an hps 400 watt bulb..

 

What is the voltage and amperage of the fixture? Is it dual voltage? The important thing is the fixture not the bulb.

 

400w hps with a digital 1000 w hps ballast with dimmer. I think
It's nanolux

 

You still haven't tol us the voltage.

 

Sorry still fairly new at this.. you want the voltage of bulb?

 

Washington state legalized marijuana last year. I'm thinking Beezly is wanting to start a grow-op.

 

The bulb is irrelevant to this discussion as I have said before. What is relevant is the fixture you are using. We need the voltage of the fixture. (Presumably you are using the bulb designed for the fixture you are using.)

 

I am not sure the 400 watt bulb will work in a 1000 watt fixture.

 

My question has gone out the window... all i needed to know is if i use the 240 will there be problms since the stoves 240 goes to the same fuse.. this is all i need to know... and i also have a 1000w bulb i guess i could use that and just use dimmer on my ballast

 

Beezly assured me via PM that he lives in Canada, not Washington state. Perhaps a moderator could help him update his profile.

Bulbs that require ballasts are generally specific to a particular size ballast. In other words, a 1,000 watt lamp would only work with a 1,000 watt rated ballast and a 400 watt lamp would require a 400 watt ballast. The type of lamp is also often specific in that you would not use a HPS (high pressure sodium) lamp on a ballast for a mercury vapor lamp. That stated, often the ballasts for these various lamps have multiple voltage input and by use of a common lead and the appropriate voltage lead the lamp can be used on several different (but standard) voltages.

You mention the use of a dimmer, by and large lamps that require a ballast do not play well with dimmers, especially not large wattage lamps.

Now as to the question...since the lamp will require only a fraction of the power available it would be best to have a different circuit or a fuse (or circuit breaker) sized to the lamp load and placed in the circuit as near to the source of power as practicable.

 

240 isn't wire or cable. It's voltage. 240V will really light up a 120V bulb, for about a half-second.

Yes.

In addition, the dryer circuit is fused and wired for more amps that your light will use. The light and it's fixture to burn to a crisp before the breaker on the dryer circuit would trip. That's why
