8 Gauge Wire, 50, Circuit - I simply worked on a g.E load center of this kind. Sure, it is vintage! Unluckily, i had to undertake the existing load center, but i changed all the opdc's. So, i made it a little more secure.
This have to be a truely old container because i see a 50 amp breaker and a 30 amp breaker i d and most important breaker at the top and foremost breaker at the pinnacle. This box ought to be a from the overdue from the overdue 1960s. Or early nineteen seventies but since you're converting the box you'll be better off with a square d. 2 hundred amp container simply located this post taylor i reply to it like a nation is in the backside. You only have a 50 in a 30 which makes makes a total of eighty amps.
So i recognize practically not anything approximately homes having rented for many years, just offered a house and become told by means of my inspector the panel is simplest a 70 amp panel and will need to be upgraded before i visit set up ac.
In your first picture, underneath the section entitled "fundamental scores", it honestly states: a hundred twenty five ampere. That is the maximum potential of your load panel. In maximum houses, the sum of the ratings of all of the circuit breakers will exceed this variety. This is because it is assumed that no longer all the loads can be on concurrently. Above that section, beneath the "standard wiring diagram", it states that there can be a maximum of 22 circuit breaker poles and that no circuit breaker can exceed 70 amperes. The latter can be the supply of the 70 amp restrict that your electrican stated. That stated, 125 amperes is too small if you are going to feature significant air conditioning. Also, you ought to have a number one breaker same to the capacity of your system in order that if that potential is passed (with out exceeding any unmarried branch breaker), the residence can be protected.
Seeing that there may be simplest a single available slot (three), it's no longer in all likelihood a valuable a/c device may be linked with out shifting things round (a minimum of). Upgrading the panel might be your most effective choice, however it would rely upon the existence (or lack thereof) of a sub panel, and the present provider supplied to the constructing (and availability of offerings in the vicinity).
