A co-worker of mine (young engineer, fresh out of school), bought her first home recently and is now dealing with contractor issues. I haven't seen the house, but from what I know it's got problems. It's a duplex with two appartments, and is pretty old. She hired a contractor (who pulled the permits) to install a second meter and seporate the second appartment to the new meter. The existing knob and tube wiring was replaced, new meter and pannel installed, but the two appartments wheren't totally seporated, and now it comes to inspection time, the contractor is unreachable. In general, does the contractor need to be involved with the inspection if he had pulled the permits? If the inspection fails (something bigger then simply picking on small things), would this normally fall back on the contractor or the home owner? I believe the money paid for the work completed ratio got a bit out of line, and the contractor has been paid more then he should have for the work that has been done to date. I'm expecting most information to be local code specific, but general info and/or what is done in other areas could help me point my co-worker in the right direction.

Hello everyone! I am new here. My question is about our woodworking shop. We installed a subpanel in the shop with 2 15amp breakers and the corresponding breaker in the main panel is a double pole 20amp breaker. the kind of breaker that is 2 breakers that have linked switches and a 20 listed on each side. We ran it with #10 wire with ground. (i know just a little about wiring so i might not be using the right lingo but will do my best to describe) The problem I am having is that the main panel breaker keeps tripping but the breakers in the shop subpanel are not. I can have the two breakers in the subpanel switched to the off position and then later find that the main panel breaker has tripped. (and this is before I even try to turn the breakers in the subpanel back on. ) Or while the power seems be running fine in the shop all the sudden the main panel breaker will trip but the subpanel breakers will remain on. I then find that the main panel breaker wont let me reset it. keeps flipping over immediately. I have found that if I unplug everything from the outlets that run off of the subpanel breakers and leave it alone of a short time the breaker in the main panel will then let me reset it. I then plug everything back in and we have power! This is getting old really quick and we are super busy with orders and can't do it all by hand and in the dark! for reference there are 2 fluorescent lights on a motion sensing switch, a space heater, a small dust collector, small sander, joiner and table saw plugged in here but none of it runs all the time and most not at the same time. problem isn't that we try to turn the wrong combination of machines on and trip the breaker this tripping is happening even in the overnight when the shop is completely shut down. thanks for any help!!
