I'm moving my a/c unit from one corner to other corner, so everything has to be buried underground, electrical and a/c tubing. I'm not doing the a/c freon part but only the electrical and just want to know what kind of wire type or gauge and if it needs to be inside some sort of pipes or tubes? thanks. I live in Riverside County, CA.

Have you ever seen an electrical fire? Can a person start an electrical fire? How do you prevent electrical fires? Any info. would be appreciated.

Is it against electrical code to have my microwave wired to the same circuit as my kitchen lights (and possibly more)? I think I recall that major appliances require their own circuit. I know electrical codes can depend a lot on the municipality but is this against general electrical codes?

Anyone pls tell. I am going to work in Perth Australia for a consultancy where they are specialist in minig and mineral processing? Pls tell what are Electrical Scope of work involved in the above? I am new to this field as i am presently working in Oil/Gas Electrical Design field?
