How Many Lights Is Safe On A 200amp Panel

peterjohn · Mar 2, 2016

hey farmers in California how many lights is it safe to run on a 200amp panel. As in safe I mean like with out setting off red flags everywhere

Your question doesnt really make any sense.
Oh youre from California, then figure 1000watts draws 9amps and 2-1000s 18amps. If you put 2 1000s on 1 20amp circuit you are pushing the limit of the factor of safety, but you should be ok.

Youre not running directly off the 200amp panel so thats irrelevant. The State of California is irrelevant. How many lights is irrelevant because we dont know how many watts each light is.

what kind of lights? what voltage?

You could do like 1000 50W incandescents and maybe still have enough room left for a ventilation fan and one of those harmonic wave machines.

what ever your wattage draw is, you need to find out what your ballast also draws, like a 1,000 watt hps with a standard magnetic ballast will be 1,100 watts. the ballast use 100 watts in itself plus bulb.
a 600 about 685watts, 400 about 465watts etc.etc.. it varies from brand to brand, and different with digital ballast.
take your total wattage, example: 1100 watt hps 1100 divided by your voltage. 110 vac. that's about 10 amps. plus on startup your light will spike, and draw considerably more, take that in consideration.
Now if your using 220vac then it would be 5 amps... also figure in you fans and all.

You can run one 200 amp light off a 200 amp panel.

If you have to ask this question on an open forum you should probably think about a day job.

Get an electrician you're going to need it!

Ima be a lil nicer and tell you its about how many amps you're going to put on each circuit. I'm assuming the breaker box is connected to the rest of the house... I really recommended getting someone who knows what they are doing look at the setup. I've been told 100w per amp on a circuit is safe and that's like 80% of total load. all that depends on the gauge wiring used. You need a lot more info before you can answer this.

Bwahahahahahah. Seen this one coming

50 amps is good for 8 1000 watts, so 32 1000 watts but then you have to figure out how much pull you need for fans pumps etc

basseye · Mar 5, 2016

you will need 100 amps to cool 32 lights right? lol

Desertboy · Mar 5, 2016

I was a little harsh maybe amps are very easy to work out

1 amp at 12v is 12w
1 amp at 110v is 110w
1 amp at 240v is 240w

Lights (Even digital ones but less) use more wattage (Amps) at start up than are rated so factor 1kw for every 600w.

Then add fans, pumps, air con, etc.

600w at 110v or 240v is the same amount of power.

That would be close to 22,000 watt light...

A 600 watt hps with ballast is close to 665 total watts...at 110vac that's 6.045 amps draw.
same 665 watts on 220vac has a 3.022 amp draw. but on start up the amps can spike to twice that.

I'm on 230v (Whole of EU is, UK used to be 240v and rest of europe was 220v but they standardised it) we always worked on 5amp per 600w which has worked fine. UK actually still mostly runs at 240v because it falls within the tolerances agreed with the EU.

I don't really know much about US electrics as far as I understand you run 110v at the sockets but the power comes in at 220v into the consumer unit as is stepped down for the sockets. 220v is available for high power items (Cookers, aircons, heaters, etc.)

Is this correct?

In which case the original poster never mentioned if it was a 110v or 220v panel which was the first thing that sprung to my mind and why I wrote the first post.
