Since we often camp in State Parks where we only have 30 amp power available for our RV, I find myself frequently using a 50-30 amp dogbone adapter.
Whenever I used the dogbone I would notice that it became very warm during use. The heat was obviously caused by the current flow through resistance in the wiring and connections inside the adapter. Current flowing through resistance generating heat also results in voltage drop inside the adapter and lowers the incoming voltage to the RV.
During a recent group camping trip, I again noticed my dogbone adapter was warm so I borrowed a Progressive Industries Adapter
and gave it a try. After running for a couple hours, I felt the adapter and it was cool to the touch. By eliminating the dogbone stype adapter and going to a high quality adapter, I eliminated the heat issue and most likely increased the voltage to the rig. Obviously I'm a big fan of the Progressive Industry stuff as I also have a surge protector from them and am using their cord ends on my power cords.
Getting one of these is a super cheap way to help eliminate voltage drop, and it's smaller and more convenient to use than the long dogbone.
