No, this is stated very clearly in the electrical code. Only one branch circuit is to be allowed connected to each individual circuit breaker no matter what the amperage is. If a new branch circuit is installed and there are no spare breakers then most distribution panels have the ability to let tandem breaker be installed in it. Tandem breakers have two terminals and two handles and have the ability to fit into a single slot in the distribution panel.
Not if it's functioning properly. The purpose of a circuit breaker is to shut off power if the circuit exceeds the rated power capacity of the wires. Don't plan to exceed the 30 Amp capacity of your house wiring; the results will be destructive.
try higher amp breaker
It's the amps that are controlled by the breaker not the volts. You can have a 600 volt 15 amp breaker, you can have a 347 volt 15 amp breaker. The breaker will trip when you exceed 15 AMPS.
Sure, but you may start a fire or damage the circuit. Kind of like saying: Can you shoot your self in the head? Sure...but I would not recommend it. Here is the deal. A fuse or circuit breaker is made to trip or burn out when a specific load is met. The engineers came up with the amperage based on a few things. But mostly to keep things cool. If something is drawing too much power (amps) then the wires will get hot. So changing a 15amp breaker with a 20 amp may allow the wires to get too hot and over heat the wires. Hot wires may melt off insulation and cause a fire. The wires may not be heavy enough to handle the load. THT
No. The 20 amp breaker is probably protecting a #12 wire. Connecting a 40 amp breaker to the 20 amp #12 wire would seriously overload the #12 wire. This means that if the load increased to a full 40 amps the insulation on the smaller size wire would most likely melt off and the wire could short out.
Anything that does not pull over 50 amps.
Use AWG 12/2 with ground.
Rule of thumb would be 8.
The fuse is matched to the size wire in the circuit the breaker/fuse it is protecting. For instance, a 20 amp breaker/fuse is used in combination with AWG 12/2 wire. A 15 amp breaker/fuse would be used with AWG 14/2 wire. If there is too much current flow in the circuit caused by either overloading the circuit or by a short in the wires the wiring would overheat and catch fire if not for the breaker/fuse. The breaker/fuse is designed to detect this and to trip or blow and shut off all power flowing to that circuit and prevent a fire. This is why you should never install the wrong size fuse. Put a 20 amp fuse on a 15 amp circuit and it would not protect the circuit as it should.
Yes, considering you can do that on 15 amp breaker easy.Experience in construction field. The worst that will happen is that the breaker will trip off after a few minutes.In the formula W = A x V. W = 20 x 120 = 2400 watts. If you want you can operate two 1000 watt lamps from a 20 amp breaker operating on 120 volts.
Ground wire connects to the ground bar, white wire connects to the neutral bar, and black wire connects to the breaker. Be sure and turn off main breaker before installing the wire or the breaker.
most of the time you will have an extra wire or two make sure you cap them off or tape them so they dont ground out. and as far as the noise in your speakers you have a bad ground and if you have an amp then you need to separate your wires running to your amp cause they are interfearing with each other and your getting road noise.
