AMPS

How many can i plug into one outlet?

[Blindman0v0]

How many what?
Electical formula

Volts X Amps = Watts

110 X 25 = 2750

So if you have a normal 25 amp circuit breaker on that line you can use 2750 easily.If eveything is in reasonable shape.

FIRE, FIRE!! Sorry but that would be the case.

MOST household circuits are rated for 20 AMP....your household outlets are rated for 15 AMP.

Now you also have to figure the curve for inrush current.....wouldn't want to be tripping a breaker when your lights come on. The initial lighting causes an additional 15% draw and I personally try to keep the total draw based on that.

110V x 15A = 1650W

This means you could run 1400 W of lighting:
1400W + (1400 x 15%) / 110V = 14.6 AMP<<< just under the 15 AMP mark.

The other outlet in the room could be used for fans, etc.....just as long as it doesn't exceed 5 AMPs.


Have a safe grow!:jointsmile:

My household lighting is 25amp and 35 amp service.But I supp0ose it varies depending on building codes in your area.But it usually a good idea to stay on the cautious side.

Everything else being equal, it is the size of the wire that is most important. The breakers and receptacles can be upgraded, but, put too much current through the wires and you get heat and then you get the fire.

But that's kinda hypothetical and doesn't apply unless you are planning on making some changes to your electrical system. For practical applications, use P4B's formula.

Everything(lights-fans) in my cabinet is pluged in to a power strip totaling ~ 370 watts and the power strip is pluged into the outlet that is shared with my washer that i'm guessing is maybe 1000? watts.. So i should be good right?
Thanks for the input!

[Blindman0v0]

The problem with putting the lights on the same circuit as the washer is the electric will surge when it first starts up and possibly blow a circuit breaker.You'll know when its all hooked up.It won't hurt anything ass long as the breaker is working but if it blows you can either put the lights on a different circuit or time the washer use for when the lights aern't turned on.

[evertking]

I thought maybe its the new fan i got it's 80 watts and its timed with the light.. i have noticed a drawn down when the timer kicks on.. another thing i thought it was was the damn heat it is hot as hell here.. Maybe i will watch next time when it kicks on and see if the washer is running.. My better half does laundry NON stop..

If your total amount of watts on that line is 1300 or 1400 you should be fine.

Thanks.

If you use 220V for your grow room it cuts your AMP load by half...and personally i prefer running on 220 i feel much safer. So if its a option you might want to consider doing that.This might come in handy and dont load a circuit to more than 70% of its load , you can go 80% but i always try to be safe.And another thing i'd do is make sure of my breaker APM rating. Each area has different electrical codes, so what might work for someone else might not work for you. Happy grow

watts/volts = amps

600w/120v = 5.0 amps
600w/240v = 2.5 amps

1000w/120v = 8.33 amps
1000w/240v = 4.16 amps

This is very helpful information......thanks.

In the United States, we do not have 240 volt electrical lines - unless one is taking electricity from a three-phase panel, which is the exception, not the rule. What we call 240 volt is actually two 120 volt lines.

Is that the same as Europe, or does Europe actually have 220/240 volts coming out of one wire?
