Maximum Wattage To Draw From One Outlet?

Hi guys I have 2400 watts I need to draw just for lights and then I have my fans etc. My question is, is there a certain number of watts I can draw from one outlet? Im worried about fire hazards and things of that nature. If I put too much load on one outlet will it automatically trip the breaker? Is that how I find out the maximum for that outlet? Is there some type of device or protector I can plug into the outlet first and plug the lights into that device? I have no idea about this electric side of this so any help would be appreciated. Thanks again everyone.
 
A 110 outlet will give you 5 amps. = 600 w light ,or 2 fans,or 1 space heater. You need 220 for the 1k watt lights. 1k watt lights actually take up 1250 Watts each. Whats your house running 110 or 220?

I live in the US I think its 110. And the dryer outlet is 220 or 240 or something like that. I have 8 300watt LED fixtures. How many can I put into one outlet?
 
I have seen 5000W from an overloaded circuit and everything worked fine.Most of your 120V circuit's are 15Amp and will handle most of what You put through them.The actual Wattage/Amperage ratio was determined by the manufacturer.Read the box.

All the outlets are connected to the same circuit in my grow room. So should I distribute the power consumption equally among the three outlets or does it matter if I put them all in the same outlet?
 
Either upgrade your box or seperate it all on 3 diff breakers. Thats the only way you could do it without overloading.Then you could spare a fan on each breaker/plug also. I had to make do like this before I got a sub box. Wasnt cheap btw.
 
I think 8 300W LED's will work fine though.Make sure the circuit is protected by a circuit breaker.A GFI if the area is wet.GFI's will pop for high humidity sometimes though so just be careful...To accurately know what You are pulling it requires 2 meter's or a really good Simpson.If You have a Breaker in the circuit and it doesn't trip then You are going to be fine...
 
A good electrical design never exceeds 80%, so 2400 watt capability = about 1920 max watts should be used with your 20 amp breaker. Check with certified elect. Fire sucks..

If all the outlet's are on the same circuit it is just like plugging them into the same receptacle.

I was certified before I had a HS diploma and after the USN I graduated from MIT with a degree in Electronic's and Motion Control as well as PLC's...

You need to know how many amps are on that particular circuit. If the circuit has a 15 amp breaker (look in the circuit box) then that circuit will handle 1650 watts...(amps X volts = wattage). It's not simply a matter of how many watts per outlet. Most circuits have several outlets on them and the total of the items plugged into it should not exceed the total amperage of the circuit. Some, things draw more wattage than others and that's why certain appliances like your washer and dryer have a dedicated circuit just for themselves. It would be better to have an electrician install a dedicated circuit just for your grow.
 
WOw thank you everyone for your help. I'm gonna go the route of if it trips the breaker it's not safe if it doesn't then I think I'm good. I can't have an electrician install a breaker just for the grow cause it'll be too obvious. And I live in a state that has really hard laws on growing so the less people know the better. Everuthi g is already setup so I guess I'm gonna plug it in and keep my fingers crossed.
 
I can talk you through the whole thing if You decide to upgrade it and I think I have a few pdf's on anything You try to tackle..That goes for anyone,any subject pretty much to dealing with Technical or hard to find subject's.

Thank you man I will message you if I have some more.questions I appreciate it a lot thank you
 
2400w will not work on a standard 110v, 15A circuit.

As @BobBitchen said, you need to stay at or below the 80% max capacity rule. 2400w is 21.8A, well above the 12A allowed in the 80% rule, and to further, it's even way higher than the 15A max rated capacity.

You need to divide your lamps up equally over two circuits (unused elsewhere in the house... you don't want hair dryers and things on it). This will put 10.9A on each circuit, leaving you with 1.1A on each for fans, pumps etc before you hit the 80% rule.
