50 amp pedastal/extension
What size wire should be used for a 50amp RV plug? I have an ample supply of 4AWG, 6AWG and 10AWG but no 8AWG. Is the 4 and 6 overkill? I will be visiting friends later and plan to park in their dr...

The rule of thumb is 6g wire (L1, L2, NEUTRAL) with 10g GROUND for 50 amp runs of moderate length. If going far, upgrade wire to 4g (can stay with 10g GROUND). The NEUTRAL needs to be the same size as the two hot wires because if only one hot wire is pulling current, all of the current is returning on the NEUTRAL.
