Most Wire Gauge 60, Breaker Galleries - The pinnacle double pole breakers are earlier than the "predominant" disconnect, which means they may usually have electricity while the wires feeding the panel have electricity. I am guessing there is a disconnect in advance of this panel, perhaps on the meter or as a standalone disconnect. Primarily based on their length, i'm guessing one (50a) is for an electric powered range, electric heater, or perhaps a subpanel. The alternative (30a) is probably for a dryer, water heater, subpanel, or some different equipment.
Quick-circuit and/or overcurrent protection gadgets (breakers, fuses, etc.), Are designed to shield the wiring downstream (after them inside the circuit). For instance. In case your panel did have a first-rate breaker, it might be sized to guard the panel wiring. The breaker would not be sized to protect the wiring feeding the panel or anything before the breaker, most effective the wiring after the breaker.
If extra than 15 amperes float via the breaker in slot four , that breaker will trip (open). This protects the wiring linked to that breaker. If more than 50 amperes flow through any aggregate of breakers on both leg a or b within the branch circuit sub-segment, the sub- segment breaker will journey (open). This saves the wiring among the sub-segment breaker, and the branch circuit breakers.
So i recognise nearly not anything approximately houses having rented for many years, simply offered a house and became informed by my inspector the panel is simplest a 70 amp panel and will need to be upgraded before i visit set up ac.
So my advice is a subpanel. The labeling says the largest department circuit breaker you may use is 70a, so good enough. Fit a 70a breaker in whichever position you could spare, both 1, 2, 3-4-five-6, (or 4-five if you may discover a double-stuff thqp270). Feed that over to a new subpanel. You are welcome to apply any other ge qline panel if you select. The next double pole breaker (50a) controls the glide of power to the decrease section of the panel. Unlike the double pole breakers above, this one must not have any terminals where wires can join. The lower section is rated for a most of 100 amperes, so the breaker defensive it ought to be a hundred amp or much less (50a in your case).
