Went to a house today to consult on a service upgrade. Problem is, I can't determine what I am upgrading from. There was no main disconnect either at the house distribution panel or outside at the meter. There was just a meter there! I think it's safe to assume, then, that if a house was wired back when this was considered legitimate practice, that it's probably a 60amp servive. However, I'd like to be able also to determine for sure what is the size of the existing wire, to see if it has to be changed to accomodate a 100a upgrade. But the wire from the meter to the distribution panel is unlabeled cloth-covered red and black, with uninsulated stranded neutral (no grounding wire). And of couse I can't tell what is coming into the meter from the mast since the poco is none too fond of us snipping off their little locks.
Any advice?
