    Question about house load calculations. We have been dividing a lot of houses into up/down suites with their own meters. If I can, I like to give the house a 400A service, but sometimes the customer does not want to pay for it if the existing loads fit under a 200A service. My question is, do...

    I have a question that I'm not really sure I know the correct answer to. If you have dwelling unit calculation that comes out to, say 195 amps, can you still use 4/O aluminum? In 230.42 it states that the conductor shall have an ampacity not less than the maximum load to be served, but in...

    Is a portable generator (the type typically used by home owners when the power goes out) a separately derived system? Or, is it considered a nonseparately derived system?

    I’ am currently bidding a job for a a triplex. Each of the 3 units will have its own 100 Amp panel, and the House panel will be a 50 amp. I am considering bringing in a 400 amp feed, is that over kill or is that the correct service size i should be using for this project?
