Breaker trip

Also yes I did replace the breaker. And it is not possible to split it. It is the last open space on the main panel.

If you've replaced the breaker and gotten the same result, then I would conclude the load is probably above 80A RMS and your meter is not displaying it properly. You'll need to measure the actual load, or at the very least add up the current ratings of all the devices on the circuit. You'll probably need a feeder and breaker rated for more than 100A, since your existing load seems to be more than 80% of that already.

Question of Fact: what kind of lighting needs this kind of juice and wire gauge?

Grow lights.

Hey now, he probably just has a really huge saltwater aquarium.

I figured it was something exotic I've never heard of.... I hadn't thought of grow lights....


I hear the greatest botanists of my generation are toiling in basements

Exactly 67 amps on each leg? And digital ballasts? So is this a mwbc? If so, it's check the load on the neutral as well. I'm going to assume you meant electronic ballasts.

mpoulton

Depending on whether his circuit is drawing the measured 67A (probably inaccurately low) or something more than 80A, this is between 16kW and 20kW+. That is one HECK of a greenhouse. That's the sort of thing the power company will undoubtedly notice and report to the DEA. Even if this is not a grow op, I think he can expect to attract some law enforcement attention with this kind of power draw at a residence.

Lol you guys are funny. Well I just upgraded every thing to 90 amp ciciute. Got a real meter, and it is just over 67 amps. So with that I am at just about 80 percent. Thanks for all the help.

Glad it worked out. Hope we weren't too snarky. We (meaning I) have a problem with thinking that we (I) am/are funny....
