One thing you can do is run during the night, saving a little on the a/c, if you run off season (not during he summer) you’ll be saving more…

Yeah I could time everything right to make sure I'm using less then what's needed.

my 100 amp is running. 4 daiken 2 ton, 1 carrier 3 ton, 3 ge dehumidifiers 60 pint, 12 gavida 1700e led, 1 mammoth p 800w led, 8 luxx 645 cmh. i stagger when the luxx light comes on. pulling 95 amps with everything on.when i stagger the light schedule 70 amps. use your amp meter. all my lights run 240v.

Yes my lights and dehu and ac will be om 240v. I think I will be like around 90 with everything on

my 3 ton uses 240 20 amp w/12 gauge wire. it only pulls 11 amp startup and settles down to 8 amp. its 100 amp per leg.

Ok. I was going to have a 60k btu mini split. Not sure how that works I believe they run all day unless I turn it off

i think the 5 ton pulls 22 amps then settles down to 18

I posted a link above for the ac unit I was looking at 1 if 3ton and 1 is a 5 ton. I think I should be ok with a 3 ton

put the light on 240 too can balance the load better instead of putting 7 amps on one leg you split it 3.5 on 2 legs.

one 3 ton can run 8 volt fl-1 led light full power with dehumidifier

Ya'll do understand you shouldn't run more than 80% of the 100 amp for an extended period of time. If your running 90-95 amps on a 100 amp line you are taking a major risk.

Whats the risk? ..... boooom? Lol

Yes, fire.
The 100 amp rating is for non-continuous loads. The continuous load rating for a 100 amp line is 80%.
Anything over 2-3 hours, I believe, is considered continuous load.

Hope everything works out well for you, a fire would probably be the most horrific thing that could happen to someone's grow, especially if you live there with your family. Good luck and stay safe

Yeah I wouldn't risk it if it's not going to work.Hope everything works out well for you, a fire would probably be the most horrific thing that could happen to someone's grow, especially if you live there with your family. Good luck and stay safe

You should consider running your LEDs on to 20 V, it'll decrease cost and consume less amps. If you have 100 A designated, you're in good shape. On the boiler plate on the AC, it will give a minimum circuit ampacity rating, That is the smallest breaker you can use for that unit.

Circuit size scribbled on the nameplate doesn’t necessarily correspond to the FLA of the running unit (NEC sets breaker sizing @ 250-300% FLA). For example my new 4 ton a/c says minimum circuit size of 40 amps, but is only drawing 14 amps FLA @ 240 volts. The “headspace” is to allow the circuit breaker to protect the circuit wiring without tripping every time the unit starts up. That said, the unit should have FLA current somewhere in the documentation, same with the dehumidifier. In regards to these 80% that is for continuous loads (run over three hours), but that’s just individual circuit sizing, not the service. Your planned room would benefit from having someone do a load calf on your home prior to this grow room addition. Also think it’s advisable to recheck whatever calc’s led to the 5 ton a/c for this grow, especially with led lights…cause my experienced is they don’t produce near the heat of older lighting schemes of high pressure sodium, and / or metal halide…

I think you should figure 3000 BTU's per light with the Gavita's. And you have a very large dehu figured.
