50/30 amp surge protectors

I have two questions that are somewhat related.

1. I seem to recall that the 30 amp circuit wiring is basically 1/2 of the 50 amp circuit. However, I had weird things happen in my camper when 1/2 of the 50 amp service at the pole failed. Results I hadn't anticipated. It very well could have been the internal wiring of the camper. I never really understood the issue. Thus my question...If I buy a 50 amp surge protector and use a 50 to 30 amp pigtail, will the surge protector work properly?

2. A friend has a Class A with a built in 50 amp surge protector. If he uses a 50/30 amp pigtail and hooks to a 30 amp pole, will his built in protector work properly?

Thanks in advance!

50 amp circuits are 120/240 volt Two hot legs divided by a neutral
30 app is 120 only one hot leg and the neutral so in this respect your "Half" is correct but as the TV sales types say "Wait there is more"

When half the circuit at the pole failed. half the RV shut down. as it should.

WHen you plug a 50 amp rig into a 30 amp outlet using an adapter. Assuming the Adapter is good The one LEG is fed to BOTH sides of the 50 amp service so everything works.. Just now at one time.

IF you have a 50 amp RV then you get a 50 amp SURGE guard. it works just fine on 30 amps. No problems. Save in some parks where ... Well the problem is the park.
