I built my dream shop which is 32' wide by 80'. It is used

Hi,I built my dream shop which is 32' wide by 80' long. It is used for mechanical work, welding and carpentry. I have a 2 post lift, large compressor, welders and carpenter tools. My load calculation came up with 186 amps for everything.I purchased the new 400 amp panel that will go on my home and my local Electrical company is changing the wire size to supply the 400 amps needed for the home and the shop.The shop I purchased a new 200 amp sub panel that technically is an interior panel installed right inside of the metal shop. So the conduit that I am running from the home to the shop is 186 feet long. And I purchased 2 1/2" conduit to run the wire through it in the ground. There are only 2 swoop 90 degree bends, one at each end and then the last 90 degree going into the building wall into the panel.If I did all my research correctly I think I have everything ironed out but want a professional to give me the thumbs up.I want to run 250,250,250 & 3/0 Rust Quadruplex Underground Secondary Distribution CableI would use the first 2 for the 2 conductors, the 3rd for the neutral and the 3/0 wire as the ground wire is that correct?

2 days ago our above stove microwave gave up the ghost and

2 days ago our above stove microwave gave up the ghost and blew one of the 4 breakers that control the kitchen and powder room circuits. I have plugged in a light to the plug in where the microwave was connected, after resetting the breaker. it has power and works fine. The microwave does not, so we will buy another one.My main problem is that ever since the breaker trip and reset, the overhead kitchen lights when on, will occasionally go off, as well as the lights and exhaust fan in the powder room. They will come back on shrtly, then do it again, unless I shut them off...then they will work fine for a period of time, then shut off on their own.Anyway, these outages do not trip the breaker. Is it possible that the breaker has been weakened by the microwave oven when it toasted out, and that installing a new breaker will fix the problem?

I have a subpages in the garage that powers 110 and 220 volt appliances. Recently all the 220 stuff stopped working. I am getting 220 between the screws on the main panel, but not 220 on the top of the subpanel. I get 110 between all breakers and ground/neutral.

One phase of dryer circuit has only ~40vac to neutral. The

One phase of dryer circuit has only ~40vac to neutral. The other phase to neutralis 120vac. The voltage at load side of circuit breaker phases is 120v to neutral. The voltage at the outlet conductors is 40vac and 120vac. Also there appears to be a loss of continuity on the low voltage phase conductor. I'm thinking either a conductor is broken or a splice is loose. But I'm stumped as to where it could be and wouldn't think a dryer circuit would be spliced. The Romex appears to route down from the panel into the crawl space and up to the outlet. Any suggestions would be appreciated. Thanks Matt

Not sure if its okay or I should worry
