Living in an apartment for a few years and just now tried to label the circuit breakers. Everything is electric. There is no gas in the building. Oven/Range, Water Heater, Baseboard Heaters, in-wall panel heater in the bathroom, fridge, Air Conditioner,... I have no to little knowledge about this stuff, so please correctly me if I am using terminology incorrectly or if I am wrong about anything.
No numbers so I'm using what I think is conventional labeling. #1 is Top Left, #2 is Top Right. Odds on Left, Evens on right. #13 is Bottom Left, #14 is Bottom Right
*#5 is a 15Amp single pole that controls the lights and outlets in both the bedroom and adjoining bath as well as the bathroom exhaust.
#6 is a 15Amp single pole that controls the outlets in the living/dining room area.
#7 and #9 make a 60Amp double pole that controls the oven/range.
#8 and #10 make a 30Amp double pole that I'm guessing controls the water heater.
#12 is a 20Amp single pole that controls the lights and outlets in the kitchen as well as the fridge/freezer.
#13 is a 20Amp single pole that doesn't seem to do anything (that I have found yet).*
That leaves the wall unit air conditioner, the three electric baseboard heaters, and the bathroom heater. Each baseboard heater has its own wall mounted thermostat. The bathroom heater just has a power knob.
**#1 and #4 need to be BOTH ON for either the bedroom heater or bathroom heater to work. Both are single pole 20Amp breakers on opposite sides of the panel (diagonal).
#2 and #3 need to be BOTH ON for the dining area heater to work. Both are single pole 20Amp breakers on opposite sides of the panel (diagonal).
#11 and #14 need to be BOTH ON for either the living room heater or the air conditioner to work. Both are single pole 20Amp breakers on opposite sides of the panel (diagonal).**
? Does this mean those heaters are wired for 240V and 20Amps? Or 120V and 40Amps? Or does each heater require TWO DIFFERENT 120V 20Amps circuits to work? Is is safe to be wired like this? Flipping either breaker OFF will shut down the heater, but is the whole circuit dead- or will the other breaker still provide half the voltage (or current)?
? Is it likely that the 30Amp double pole (#8 and #10) IS the water heater? And is it likely that there is a 20Amp breaker (#13) that doesn't do anything?
