Re: [RE-wrenches] Square D 225A load center

Almost right Christopher. NEC 705.12(2) allows the ratings of the overcurrent devices supplying power to the bus bar to be 120% of the busbar rating. For a 225-amp busbar that amounts to 270 amps. So a 200-amp main breaker and a 70-amp back fed breaker from the solar system. Or a 225-amp ma

Re: [RE-wrenches] Square D 225A load center

Ahhh - I think I get it - you get the 20% of the 200 amps (so 40 amps) + the extra 25 amps because the buss is only running at 200 amps? I just saw you emailed me... Christopher Christopher Freitas Director of Research and Development OutBack Power Systems, Inc. [EMAIL PROTECTE

Todd, I think you are putting yourself at risk. What if you have a claim and they deny it because you did work on a roof? My insurance cost is $850 per year for $1M. I'll let the group know what my agent says about these other classifications when they get back to me. Larry Crutcher Star

Re: [RE-wrenches] Square D 225A load center

Glenn - That is an awesome load center but I believe there is also one without the meter/CT/disconnect provisions that is made for indoor applications. I will certainly be looking at this for new construction in the future though. Thanks! Andrew On Thu, Dec 4, 2008 at 12:23 PM, Glenn Burt <
