Hello all, Had a pre-inspection done and inspector noted corrosion (somewhere in panel). I didn't see anything at first, neutral bars and service panel overall look new. No water inside basement, 200-AMP service 11 years old. And then, on close inspection, some of the lugs looked weird. I took a picture of the worst. I 'ranked' them 1-4, 1 being what i think is normal, 2 is normal+ some copper colored dust stuff on the bottom corner, 2 is more of that, and 3 and 4 include white stuff on the lug and green on the wire. [ATTACH]95499[/ATTACH] #4 is the worst by far in the panel, and oddly enough, is a double 30 AMP breaker with the top of the double breaker looking normal, wtf? I popped one out and the buses look normal as far as i can tell. The little white cap things on the screws, about half of them seem in the process of falling off, a few are off. Either way, i have to get an electrician out to sign off/fix. I was considering replacing some of the breakers myself (since i've done before) to save cost maybe. I don't want to get some junior in here telling me a need a panel replacement when it might not be necessary. Advice needed! Thanks!!! [attach]95501[/attach]

I have a deck, it's completely covered, waterproof and has 3 3/4 walls and a little area to squat through to get underneath, it attaches to the back of the house and the basement is visible through a window. I want to cut the female end off a 10 AWG extension cord and run it into a box under the deck on the house, waterproof I assume, (it would be easier if it wasn't - you'll see in a minute) and then join it to 10 AWG THHN in the box which will run through the wall, in conduit of some kind and into a box inside - most likely or directly into a sub box where it will attach to a breaker. I'm unsure how to connect EMT conduit, if I use that, to the outside weatherproof junction box, and likewise if I use LT flexible conduit how to attach that to a metal box inside? It would be easier for me to use the EMT given a 90 turn inside I'll need to make. Thanks very much, Jim The photos show the outside starting point and the inside point. Someone had previously put some UF through a hole to power a GFCI and light under the deck (both in waterproof boxes).
