Electric Question

Hello everyone I am using right now a C.A.P lighting 4 MLC XT it's a 4 outlet 240 volt with built in timer. It also calls for a 30 Amp breaker.

I've been using it for over a year and its perfect. Now I expanded my grow and want to add 2 more lights. I just purchased the Solatel Power expander, It's a 6 outlet with a 120 volt trigger for a timer. It also calls for a 30 amp breaker.
Question is that correct? If I was using 4 1000w ballast with a 30 amp breaker why would they call for a 30 amp also with 6000w @ 240 volts
If I run all 6 ballast @ 4.7 amps each thats a total of 28.2 amps is that ok?

you should only run about 80% of what a breaker is rated for so your 30 amp breaker should not be loaded over 24 amps.you are under the the 30 amp limit so it should work but when lights kick on,the ballast will draw 2-3 times its rated draw for a few seconds. the breaker can handle some overloading for the short time but since you are so close to the max,I think all the ballasts turning on at 1 time will cause problems. can you move 1 light off the circuit? or set 1-2 lights on an opposite light cycle?

P= power I= Amperage E= Voltage

P=IXE Therefore, 6000w/240v=25A. You need a 2 pole 30 A breaker.
