These two were in a back room. I think the one on the right use to be the main at one time and the one on the right use to be a sub. The power to this house was not on as you can tell be the first set of pic. This house was built in 1917.

Hi to all,
Barron, it is hard to determine the service amperage from what you have posted, but remember the available amperage is the lowest of the rated components. including:
SEC
Meter
Panel
Main disconnect
I believe that the first picture that you posted shows the edge of the electrical meter which appears to be on a round base, If I am correct about that being the Meter, Then the supply cannot be bigger than 60 amps.
The service entrance should not be AWG 6 as this is too small for an SEC
Back in 1917 when the house was built the service probably would have been 25-30amps, but it is fairly rare to see a supply now that is that small.
I would site the service as being Probably a maximum of 60 amp, and recommend that the system be further evaluated by a licesned electrician due the the limited supply and the age of the system.
BTW many carriers will not insure a home with a 60amp supply

This is a classic “call the electrician for evaluation”. You can easily say it is a maximum of 60, because of the 6ga wire. That is enough to suggest a service upgrade is requied.
