Yes it is wired with copper 2 wire is also known as 14/2 wire is use for switches,outlets,lights. and a 15a outlet should only be on a 15a breaker the main power feed to your meter to your panel is aluminum and can take more of a load than copper.
In the US, 15 amp receptacles can be installed on 20 amp circuits if there is more than one receptacle on that circuit.
Copper wire can carry a larger load than aluminum wire of the same size.
Not unless the wire going to the refrigerator outlet is AWG 10/2. If it is wired with 12/2 wire then you must use a 20 amp breaker. Using a 30 amp breaker is dangerous and a fire hazard.
A 100 amp residential service requires a size #8 copper wire, it should be insulated in green.
Not legally because the rating of the 30 amp receptacle would have a 50 amp breaker ahead of it. If you reduced the feed breaker to 30 amps and still use the #6 wire, this would be within the electrical code rules.
10 AWG.
the size of the wire that you need to run depends on the the amperage of the device/appliance you'll be hooking up to that line. Use #12 wire for 20 amp, #10 for 30 amp, #8 wire for 40 amps and #6 for 50 amps. Hope that helps.
At 120 volts a 15 amp circuit wired with #14 wire used for a dedicated light circuit do not install any more than 1400 total watts in lighting. If used for an dedicated outlet circuit do not install more than 8 outlets.
Not without moving up two wire sizes from a #14 copper wire rated for 15 amps to a #10 copper wire rated for 30 amps.
A 15 amp circuit breaker is used to protect a # 14 copper wire which is the minimum size wire that can be connected to a 15 amp receptacle.
Not unless the wire going to the refrigerator outlet is AWG 10/2. If it is wired with 12/2 wire then you must use a 20 amp breaker. Using a 30 amp breaker is dangerous and a fire hazard.
You can use the wire rated for 20 amps on a 15 amp receptacle but you can not use a 20 amp fuse on any device rated at 15 amps. This is a tricky part of the code about receptacle outlets, You can use a 15 amp duplex outlet on a 20 amp circuit. (duplex outlet two devices can plug in) If it is a single outlet then the outlet must be rated 20 amp. NEC table210.21(B)(3). ============ A 15 amp duplex receptacle can be wired to a 20 amp rated circuit. This means the breaker OR fuse protecting the circuit can be rated 20 amps if the wire is also rated at 20 amps (12 AWG). --Sparkfighter
30 amp wired with AWG # 10 wire.
Assume a single breaker controlling a number of outlets. The black wire is HOT, the white wire is Neutral and the green or bare wire is Ground. The wires and outlets should match the rating of the breaker in Amps. Typically 15 A for 14 Gauge wire. (I prefer 20A outlets and 12 gauge wire). You must calculate the expected load at each outlet. The electric code may be different in each locale, but 8 to 10 outlets on a circuit might be typical for general usage. That is over an amp per outlet. If you had a situation where you knew you would be plugging in a high amp device liek an electric heater you might only have 1 outlet on circuit. You wire the outlets in a circuit in parallel and make certain each is wired identically. The Black wire should always be on the copper colored screw and the white on silver screw and the ground on the green screw. For a couple of bucks you can buy an outlet tester. It is usually yellow with a three prong plug and lights that tell you if an outlet is wired correctly with power turned on. The lights identify problems based on which lights are lit.
You use the correct size breaker depending on the size wire in the circuit. If the circuit is wired with AWG #12 wire use a 20 amp breaker. If it is wired with AWG #14 wire then use a 15 amp breaker.
Yes, a 20 amp breaker requires AWG # 12 copper wire. A 15 amp breaker requires AWG # 14 copper wire.
AWG # 8 copper.
Yes you can. The existing 30 amp breaker on the two conductor #10 wire will have to be changed out to a two pole 20 amp breaker. The reason for this change out is that the new 20 amp outlet is only rated at 20 amps maximum. If the 30 amp breaker were left feeding the 20 amp device, It would be unsafe as it is 10 amps higher that the manufacturer's specifications of maximum amperage handling capacity of a 20 amp device.If the 30 amp circuit is only 120 volts, the neutral will have to be lifted from the neutral bar of that circuit and that will be the second wire that will be connected to the new two pole 20 amp breaker. This action will give you 240 volts across the new 20 amp outlet.
A 100 amp residential service requires a size #8 copper wire, it should be insulated in green.
