Forum Title: Homeline panel question
Hey guys. Just looking for your opinions. We are in the process of doing some upgrades to a retail space in a strip mall that has been vacant for over 1 year. This space is served by a 200 amp Homeline 30 space breaker panel. This panel contains a labes that states "Total Circuit Breaker Handle Rating Not To Exceed 185 Amperes Per Branch Circuit Connector". We have a new electrical inspector here, and he is interpreting that label to mean that 185 amps is the total breaker handle amp ratings for the entire panel. I interpret that to mean the max rating for each buss stab. What do you guys think?

30x 15A is 450A. They're clearly not referring to the entire panel. "Branch Circuit Connector" sounds like the stab. I agree with you; 185A max individual breaker rating.

Leave it to a company controlled by lawyers and engineers to plaster their products with vague, confusing, and grammatically questionable statements. Not that I'm picking on Sq D .... it's hard for mt to recall any product whose labeling and instructions were a joy to read; "clear as mud" seems to be a universal these days. Yet ... let's look at that statement a bit closer ... assuming, of course, that you repeated it correctly! "Branch circuit connector" would seem to refer to the point where the branch circuit wire, uh, connects to the panel. That would be the 'out' screw / clamp on the breaker. By extension, it might also apply to where the breaker attaches to the buss. Before that point, it's not a 'branch' anymore; it's a 'feed.' "Handle rating" is a bit more questionable. I have yet to see a handle that was expected to carry ANY current. I think they mean the number printed on the handle, indicating the rating of the breaker. "Total" suggests the sum of more than one. I can see this situation, when the 'tandem' breakers let you hang two breakers off the same buss tab. "185" is a strange figure. I can't say I've ever seen a 185, 190, or 195 amp breaker. Just 175 and 200. They can't be referring to the 200 amp main breaker that came with the unit; not even Sq D would deliberately break their own rules . Naturally, if the main was 175 amps, it would not be a '200 amp' panel anymore. Tandem breakers? I've seen tandem 30's .... but never tandem 90's. It would be a challenge connecting a pair of #3 wires in a single breaker space! So, we're left peering at fine print that says, in effect, don't use equipment that doesn't exist in this panel. Why couldn't they just say 'don't mount breakers with ratings in excess of 176 amps on this panel?'

I vote for "per stab". I think it's actually pretty clear, when compared to your average label warning.To convince your inspector, get in touch with the manufacturer and see if they have any clearer documentation on your particular panel model. If not, they could probably have one of their engineers send you a quick letter on company letterhead, which you can present to your inspector.Good Luck!
