Mar 29, 2016 · The one thing to worry about is that you have the potential for 60 amps of 120 volt power to run between the panel and the genset. Each wire is 10 gauge and each wire is protected at 30 amps. So the wire can handle this, the breaker protects the hot wire. The trouble is the neutral. On a 120 volt circuit, the neutral carries current. Wire size calculation – Selection of the appropriate line When calculating the cross section according to the above formula, the result is a value in square millimeters \(mm^2\). This will rarely fit exactly on a commercial cross-section.

As long as neutrals and grounds are not bonded together in the sub-panel this is rarely an issue. Now if grounds and neutrals are joined together in the sub-panel, the current of all the 120 volt circuits that are operating will travel on the metal conduit, and the neutral wire, as well as the ground wire if present. This is multiple paths. Further confusion can be caused by the term "jack", which is used for both female and male connectors and typically refers to the fixed (panel) side of a connector pair.

How Load Affects Voltage Drop . Voltage drop increases as the load on a circuit increases, and overloading a circuit contributes to excessive voltage drop. In other words, if you put too many loads on one circuit and exceed the standard 80 percent safe capacity (1,440 volts for 15-amp circuits; 1,920 volts for 20-amp circuits), you'll add unnecessary voltage drop.
