The breakers literally fall out out the panel or else sit at an "angle". Ironically, it's a PITA to get them onto the bus. BTW, I'm extra angry at SQD because I just came in for lunch from a commercial job with QO stab in breakers. You practically have to beat the 3 pole breakers onto the bus. That's ridiculous.

UHF All static, all day, Forever MVM join:2002-05-24	UHF MVM 2012-Aug-6 1:41 pm I don't use the 3 pole QOs, but the one and two poles are the same price as Cutler and GE at the big box stores. Never had any issues getting any of them onto the bus. But then, I've probably only installed 100 of them in my lifetime, probably a tiny fraction of what you've seen.

There's something to say for bolt-on breakers of all manufacturers. Install once and forget them. Can't fall out, sit at an angle or have problems with high resistance stab connections resulting in catastrophic failures.

nunya LXI 483 MVM join:2000-12-23 O Fallon, MO	nunya MVM 2012-Aug-6 4:39 pm I think they all should be bolt-in. I used to like the SQD bolt in stuff, but they went to plastic retainers on the outer rail. All manufacturers went to plastic, but most slide under (BR style). SQD basically have to be "smashed" on.

SQD had really nice breakers, they'd trip very quickly on a short, which was uncommon at one time.

SQD had really nice breakers, they'd trip very quickly on a short, which was uncommon at one time. We've tested Sq D breakers that would not trip until they disintegrated. All circuit breakers should be manually exercised ON/OFF on a regular basis. Especially those in harsh environments. That's why fuses are a much better and reliable protective device.
