A recreational vehicle, or RV, campsite must be wired to supply the 20-amp needs of the most modest truck or popular-up camper, the xxx-amp needs of a C-Class motorhome and the fifty-amp needs of the largest converted motor coach. The near user-friendly way to establish these supplies is to wire a campsite claw-upwards box, called a supply pedestal. These are weatherproof, self-contained upright boxes fitted with 20-, 30- and 50-amp outlets all subscribing to the American National Standards Institute designations for plug/outlet shape and size. They are manufactured with integral circuit breakers, and tin can be purchased with a pedestal light and a usage meter.

Step 1

Switch off the main breaker box which supplies the RV campsite by throwing the 100- or 200-amp master switch to "Off." Take out the dead-front panel, so exam across the power conductor and neutral bus with a voltage meter to ensure the box is asunder. Ostend that two big hot wires, 1 neutral and one footing, feed the power conductor, the neutral bus and the ground block in that order. This configuration is chosen split single phase, and tin supply a 50-amp campsite.

Step ii

Install a 50-amp double-bus circuit breaker in a vacant receiver. Using Blazon UF–rated, 4-usher 6-approximate wire, connect the two 120-volt hot wires--typically color-coded black and red--to the 50-amp breaker'south terminals. Information technology is unimportant which color mates to which final. Connect the neutral wire to the neutral bus, and connect the greenish wire to the basis bar.

Step iii

Site the campsite pedestal where it is protected from accidental contact and the elements. Run the wire from the breaker box to the pedestal, securing it where it cannot exist damaged, using cable clips or plastic zip ties.

Step 4

Follow the pedestal manufacturer'south instructions to remove its case front and install supply. There is usually a grommet-protected knock-out toward the base of the pedestal through which the wire is inserted, and a connectedness console nearby with four terminals. Spiral the interchangeable carmine and blackness hot wires to their marked terminals, the neutral wire to the white-painted final and the footing to the light-green-painted final.

Reinstall the pedestal instance front and the breaker box expressionless-forepart panel, then throw the master switch to "On" to reinstate supply. Using a voltage meter calibrated to 240-volts, examination that power is supplied to each pedestal outlet.
