I need to install a new 100 amp sub-panel in my beach home in Chelem, currently I have 3 – 20 amp backers taking care of the entire house. The new sub panel will be about 85 ft from the service meter My question is what size wire should I run?

Re: Sub-panel wire sizes?
Hi If you are going to use copper THHN or THW wires use # 4. If you are hooking up sub-panel make sure to isolate the ground to the sub panel which means that all the ground wires will connect to the ground bar and the sub-panel and all the neutrals connect only to the neutral bar, also remove bonding screw from the neutral bar.
