What is the most common RV Socket and RV plug type?

The most common RV socket and plug type used in North America is the NEMA TT-30. This type is prevalent for supplying power to recreational vehicles (RVs) at campgrounds and RV parks. Here are some details about the NEMA TT-30 socket and plug:

NEMA TT-30 Socket (Receptacle):

The NEMA TT-30 socket is a 30-amp, 120-volt AC receptacle.

It has three prongs: two flat blades (hot and neutral) and a rounded pin (ground).

The TT-30 socket is commonly found on the electrical pedestals at campgrounds and RV parks, allowing RVs to connect to the power supply.

NEMA TT-30 Plug:

The corresponding plug that fits into the NEMA TT-30 socket is known as the TT-30P.

The TT-30 plug also has three prongs corresponding to the socket: two flat blades and a rounded pin.

RVs use the NEMA TT-30 configuration for their electrical connections, allowing them to draw power from standard 30-amp electrical outlets found in many camping sites. It's important for RV owners to have the appropriate power cord with a TT-30 plug to connect to the campground's electrical supply. Additionally, some RVs may have adapters to connect to different types of electrical sockets if needed.
