Can I add more breakers to my panel?
If there is no open space, local electrical codes might allow you to replace a single breaker with a tandem breaker, which supplies power to two circuits. Make sure you do not overload your service panel. For example, a 100-amp service panel could have circuit breakers that add up to more than 200 amps. This is normal.
How do you tell if you can add a circuit breaker?
If all the slots in your fuse box contain breakers, you assume it’s full. However, take a look at the diagram inside the door. It indicates how many circuits a breaker box can handle. If you see a 20/40 notation, that means your box has 20 spaces for breakers and the capacity to operate with 40 circuits.

How many amps is a 30 amp double pole breaker?
30 amp capacity. Safe maximum: 30 x 80% = 24 amps. 120 volt 20 amp outlet can be installed on 20 amp breaker, but not 15 amp breaker/ use 12 ga wire.
How far can you run a 30 amp wire?
The reality is that you CAN run a 30A load on a 10ga wire but code calls for only 80% of load or 24A. Which is the same draw a 5500W element will draw. Length is the real issue, 50′ is the max for 10ga at 30A, you go up to 8ga for more than that.
How many outlets can be on a 15 amp circuit?
Can lights and outlets be on the same circuit?
Basic answer to your question of can a mixture of lights and receptacles be installed on a single circuit is yes. Check with local authorities on those limitations but yes it can be done. Also be sure to install a GFCI receptacle, not a conventional duplex receptacle.
Is it OK to mix 12 and 14 gauge wire?
