What is the difference between 10 2 and 10 3 wire

Some people will claim that there is no difference, or that the AWG system is fine and just needs to be replaced with the metric system, but that is not the case. Save my name, email, and website in this browser for the next time I comment. In fact, it is better to let them handle these things. Table of Contents. This is because the cable contains 4 gauge wires, insulation for the individual wires, and the cable jacket.

This applies to most home dryers, but you should always double-check the required amperage of your appliances before running cable to the outlet. Make sure the cable is placed on a dedicated circuit where it can reliably draw 30 amps.

Overloading a circuit can lead to a tripped circuit breaker or an electrical fire. However, you must run the cable through a conduit in many cases to protect it from breakage. There is some leeway when sizing wire for voltage drop per the NEC, but for circuit breakers, it's rather clear cut. Appendix B, tables. FastEddieG said:. You would be interested in this thread then.

It's a recipe for wires burning and starting fires. No way would I ever design a circuit in that manner. I would maybe use the exception as a feild fix for nuisance tripping, but never as a new design.

Aceman Well-known member. Where do all these people come from? None of them seem to be electricians, they don't know code, but they still manage to try and convince everyone on this forum that they know what's best. Joined Sep 4, Messages 4, Location In the cornfields. Well said Aceman. Some of the electrical advice I've read on this forum would burn your house down. I don't claim to be an electrician or to know and understand the code, but I'm curious for my own knowledge what is dangerous about using a wire size that correlates with the breaker size?

GeorgiaHybrid Well-known member. I try to listen, ask questions and learn somethings while on here. You can also run a wire sized to the breaker but it is not required under the requirements in the code for those circuits. GeorgiaHybrid said:.

So my question is, what is dangerous about running wire properly sized to the breaker instead of thinner bare minimum wire as stated by code for that application? FastEddie, Read what I posted. I also stated that you can run a wire sized for the breaker. You can use either for a 50 amp receptacle. The power demand of ranges varies depending on the rating of the appliance, but in most cases, a amp volt circuit is required, wired with 6-gauge wire.

The manufacturer recommends a 40 amp volt service. Each oven, on maximum broil only consumes watts — or watts in total…. How many amps will 10 gauge wire handle? If our wire is copper, that 40 AWG conductor, with a 9. Remember that the cable must have an extra hot wire.
