I want to install a new PVC mast and hood; a new 200A meter; 2 100A outdoor breakers. One breaker will feed my existing 100A panel.
The other 100A will feed a new air handler and a couple of receptacles in the basement.
What is the maximum distance allowed from the mast head to the eyelet holding the utility feed? I want to mount the mast and new meter pan and all the other new stuff before I call the inspector and he calls electric company to switch it over. What do I use to connect the two 100A outside CB's to the new meter base? And to connect the new 100A CB to the existing 100A panel? What is the code with respect to proper fastening of the mast to the house? how about fastening the branch circuit wire to beam members in the basement? I do not know the proper names for all the components or proper wire size/ types. The existing ground electrode looks like crap. the clamp is loose on the electrode, and the solid wire to it is a single solid conductor of unknown metal. I doubt if the electrode is 8 feet into the ground. What gauge should this wire be, and where do I attach it? By what means do I bond it? The old panel has a 220/50A branch circuit going to an outside disconnect which is adequate for the new heat pump.
There will be a few vacant spaces in the old 100A panel but I'd prefer to put in a sub-panel off the new 100A branch in the basement. (as opposed to just a disconnect and only power the air handler) What is the code with respect to mounting the sub-panel? How far from the air handler can the sub panel be? Can it be mounted on the foundation wall on a piece of plywood, or a piece of plywood where a beam and post intersect? The air handler specs are: Circuit Amps:51.9/60.0; Minimum Circuit Ampacity:68/79; Maximum Circuit Protection: 70/80. What kind of subpanel, and what CB for the air handler.
What wire gauges/types? Can I use copper, or is it too expensive? my branch from the outside CB to the air handler location will be about 50' depending on the location of the sub-panel. When I electric company is on there way over to bring a new feed to the eyelet off the pole and tie in my mast, I'll pull the meter and switchover the existing 100A panel to the new 100A outside CB. Comments? suggestions? Thanks!
