i agree with the guys, JUNK IT. i have one in my house , belive it or not they actually trip. real old panel. but my neighbor had one. he wanted to run 230 to his shop, after looking at the price of a new 20 circuit panel& all the brekers we needed to replace,we still come out cheaper.it seems the reason there so high is there was a class action lawsuit against them in the 80's. the reason i say this is because i saw the memo.again just throw that junk away & put in a quality panel, that way both you & your friend can sleep better at night.ERWIN
