100 amp sub panel for detached garage
Calling on electricians or anyone with good experience and knowledge with electrical work. I recently just updated my electrical service in my home, to 200 amp service with a new panel box. I’m now looking to install 100 amp sub panel in my detached garage. From my main panel, situated at the front the house, the distance required to run wire to the garage would approximately run 100′. The length of the actual house is about 45′, & I would need to add another 12-15′ of wire upwards along the side of the building for an overhead application. From the end point of the house to the garage would be approximately another 40′ +, bring the total to 100′ + in distance/length, as mentioned earlier.
1) What size of service wire is needed for 100 amp sub panel, based on the distance/length of wire (100′ +) factoring in voltage drop, for both both copper and aluminum wiring?
2) In addition to the size of wire, I’m also looking to see if there is an armour cable wire that would house all the wires required (hot, neutral, ground) in one larger size cable jacket for a 100 amp sub service wires that could be used externally, since it would be exposed to the elements, without having to go the PVC conduit method?
Reason for looking at an armour type cable that encompasses all needed wires is it would offer a simpler method to mounting the wire to the side of the house instead of using PVC conduit and feeding the wire through. The challenge with PVC would be bending around two protruding chimney stacks that run the full height of the house, plus another sweep or two that might be needed internally from my main panel box.
Hoping for some great knowledgable folks to help answer these questions and offer any valuable advice or guidance. Sincerely appreciate all the help!
