This is solved with dogbone having NEMA 14-50 female connector on one side and male TT-30 connector on the other side. NEMA 14-50 male connector simply can’t fit into TT-30 outlet. On the other hand, TT-30 has two flat prongs, one live and the other neutral, and a round prong for the ground. The NEMA 14-50 connector has 3 flat prongs, two for live wires and one for the neutral, and one round for the ground.
The first problem is the difference in the physical shape of NEMA 14-50 and TT-30 connectors. The 50 to 30 amps dogbone adapter works by solving two problems.

This means that this connector can provide your RV with up to 3,600 watts of power, which can be a somewhat limiting factor for powering more than a single AC unit in your 50 amps RV. It simply and directly provides one 120 volts and a maximum of 30 amps current between an outlet and a device, in the case of an RV that is the transfer switch. While the NEMA 14-50 connector has two live wires, the TT-30 connector has just one, besides the required neutral and ground connectors/wires. How Does The 30 Amp TT-30 Connector Works? RV Power Adapter// 50 amp Adapter to 30 amp > Check out the video below: In addition to these two live vires, this connector also provides neutral and ground connections. In the case of the 50 amps RVs, the transfer switch does not combine these two lines into 240 volts but uses them somewhat independently as two separate 120 volts inputs. NEMA 14-50 does not provide 240 volts, instead, it provides two 120 volts lines, and machines that need 240 volts through their own wiring combine them into 240 volts.Įach of these lines is capable of providing up to 50 amps of current, which means that the whole connector can supply up to 12,000 watts of power. This fact is very often cited as an assumption why you should not be able to connect a 50 amps RV to a 30 amps shore power, but you know what happens when you assume.
The connector which every 50 amps RV uses is called NEMA 14-50 connector.īesides in the RV, it is often used in some other applications where 240 volts alternating current is needed.
