PARK North Extension <br /> <br />Marshall, <br /> <br />I have decided to run all of the feeders with the same size conductors and pipe size. <br />The following list shows the projected Voltage Drop at each pedestal, these <br />calculations are based on each RV drawing 50 Amps Simultaneously. The RV <br />pedestals will be pedestal mounted Loop feed type, equiped with (1) 20 amp GFI <br />outlet, (1) 30 Amp 120 Volt receptacle, and (1) 50 Amp 240 Volt receptacle. <br /> <br />RV Pedestal # Typical Max.
