Power adapters per Mex's post are just power plugs and wire, no protection at all. For example to plug a 50A rig into a 30A pedestal the adapter would connect the 30A male plug to the 50A female plug as: neutral to neutral, ground to ground and 30A hot to both 50A hots. This provides 120V to both 50A hots but limited to 30A total instead of 100A. Very few rigs have 240V appliances so lack of 240V is a non issue.
I carry adapters for all situations: 20 to 30 to 50 and 50 to 30 to 20. With my 50A rig I use the 20 to 30 to 50 as required.
I also often check the pedestal with the 50 to 30 to 20 and a 3 light household tester. This is an excellent test for 20 and 30 pedestal plug wiring issues. It's a good test for 50A since it will verify the ground, neutral and one hot. It is not a load test but I could also plug in say a ceramic heater.
