To prevent or ameliorate this voltage drop, larger-size conductors can be used for long runs. One rule of thumb is to use one size larger wire for every 50 feet of run from the power supply to the connection point; the electrician should be able to make this determination on-site.Also,...
Also, for copper (Fig. 28.2, right)—often an excellent conductor (58·106 S/m)—one has to be aware of the copper oxide protective layer developed in air. Also important to observe is if the copper wire is polymer coated or not. Both types exist. Although the conductivity of silver ...
For example, a No. 12 flexible cord has a larger diameter wire than a No. 14 flexible cord. Choose a wire size that can handle the total current. Remember: The larger the gauge number, the smaller the wire! American Wire Gauge (AWG) Wire size Handles up to #10 AWG 30 amps #12 ...
