Welcome to a comprehensive guide on 50 Amp shore power wiring diagram. A 50 Amp shore power system is the most common size used for RVs nowadays. The system is capable of delivering 50 amps of current at 120 volts AC, which is sufficient to power up all appliances and gadgets inside the RV.
Understanding the Basics
Before diving deep into the wiring diagram, it’s important to understand the basic components of the system. The main components of a 50 Amp shore power system are-
- Shore power inlet
- Transfer switch
- Distribution panel
- AC appliances and gadgets
Shore Power Inlet
The shore power inlet is the receptacle, where the shore power cord plugs in. It’s usually mounted on the side of an RV and can be easily accessed. An inlet rated at 50 Amps is required for this system. The inlet has three prongs- two hot legs and one ground, which carries a current of 120 VAC at 50 Amps.
Transfer Switch
A transfer switch is a device that switches between the shore power and generator power or inverter power depending on which source has the highest priority. The transfer switch is mounted inside the RV and is connected to the shore power inlet and the generator or inverter output. The switch can be automatic or manual. The automatic switch senses the presence of shore power and switches automatically. A manual switch needs to be switched manually.
Distribution Panel
The distribution panel is the heart of the power system. It’s responsible for distributing power to all AC appliances and gadgets inside the RV. The panel has circuit breakers, which protect the appliances from overloading and short circuits. A 50 Amp distribution panel has two hot legs and one neutral leg, which are rated at 50 Amps each.
AC Appliances and Gadgets
The AC appliances and gadgets include air conditioners, refrigerators, televisions, microwaves, and other similar devices that require AC power to operate. These devices are rated in watts or amps, and their total power consumption should not exceed the rated capacity of the system.
Wiring Diagram
The wiring diagram of a 50 Amp shore power system is relatively simple. The shore power cord plugs into the shore power inlet, which is connected to the transfer switch. The transfer switch is then connected to the distribution panel. The AC appliances and gadgets are then connected to the distribution panel through separate circuit breakers.
