No, you can never mix wire sizes in a circuit.
Use AWG 12/2 with ground.
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.
is it polesible to run a range of appliances on a single 15amp receptical
Matters how many it has on it. <<>> A properly wired receptical will only have one black, one white and one ground wire attached to it. These wires will be pig tailed from the incoming and outgoing cables that are located in the receptical's junction box. The ground wire that is spliced with a pig tail connection also will first goes to the ground screw before it is terminated to the receptical's green ground screw. The reason for splicing the wires this way is to prevent opening the circuit neutral if and when you have to change the receptical for a new one. The same neutral can be used as the common wire from another breaker that might not be turned off when you shut the breaker off to change out the receptacle that needs repllacing. Opening the neutral from another circuit will have that breakers voltage on it. If your body gets between the open neutral and a ground you will receive a sever shock from the current that the other circuit's load is carrying.
For a 1200-watt amplifier, the appropriate gauge of speaker wire typically depends on the length of the wire run. For runs up to 50 feet, 12-gauge wire is generally recommended to handle the power without significant loss. If the run exceeds 50 feet, consider using 10-gauge wire to ensure optimal performance and minimize voltage drop. Always consult a wire gauge chart for specific applications to ensure safety and efficiency.
4 gauge
its the blue wire, alot of ppl run it off the distributor, but why, when these cars came with a tach in the Si trim, just splice into the blue wire on the gauge cluster harness
6ga should be used. It might not be against codes where you are,and you might have a 50amp installed for something that only uses 40amp, but it should be done right, and 6ga should be used off of a 50amp breaker.
The longer the run, the bigger and heavier the wire will need to be. The AWG number denotes the diameter of the wire: the smaller the AWG number, the bigger the diameter.
14-3 Is the standard wire use for residental smoke detectors.
yesAnother (corrected) answer.NO! The circuit breaker is there to protect the wiring from overheating. It wouldn't matter where on the circuit you decided to put the 14 gauge wire, you would need to change the breaker to 15 Amp if you did that. Using 14 gauge wire on a 20 amp circuit is a fire hazard and contrary to UBC. Contact your local building and zoning department to verify.
For low voltage wiring, typically smaller gauge wire is used, such as 18 or 20 gauge. The specific gauge will depend on the current requirements of the circuit and the distance the wire needs to run. It's important to consult the manufacturer's recommendations or local building codes to determine the appropriate wire gauge for your application.
