I am having a new shop built on Friday.The shop is located 250 feet from my power meter.
For a 240 volt 100 amp service in the shop, the online calculator says I need 2/0 AWG Aluminum or 1AWG copper.
I have underground service to my home and the wires leading form the meter run under the slab to the 200 amp panel in the bedroom closet. Running a wire from the panel in the house to the shop will not work as I cannot get the wires into the house. The meter also has separate wires running to a 100 amp service panel in the add on washroom. There is a separate conduit running to the meter box that feeds this portion of the house. The wires feeding the 100 amp service are too small for what I need at the shop. Plus I have the same issue getting the wires into this panel box as well.
What do I need to do to get the power run to my shop? Is there a way to tie 2/0 AWG into the meter? I am guessing the meter is already crowded since it has wiring for the 200 and 100 amp service running to it. I am guessing there will be no room to run additional wiring to it as is.
My service line to the shop will be under ground. What wire type should I use?
