I have a brother and it works fine for what I use it for (rarely used).
I do know this: Whoever did the wiring at work and labeled the panel needs their hand writing to be checked. Just scribble, can't even read it. On mine at the shop I made labels that are MUCH easier to read & understand. Legible labeling ought to be NEC if you ask me. Maybe it is; if so those crackheads that did the work didn't do it to code. One is loosely scribbled "fan" (20' diameter ceiling fan) and when I went to weld the other day, welder wouldn't come on. Nothing marked "welder". Turned the fan on, welder came on. Then Saturday we needed the fan. Went over to the controller; nothing. The breaker under the "fan" breaker was the only one off, turned it on, controller lit up and then it worked. That one is not labeled at all. Idiots.
