Advice on surge guards, please

Stooopid question time ....Will it do any good to have my 50 amp surge guard hooked up to a 30 amp post (my coach has 50 amp service, so I would use a pigtail), or do I need a 30 amp sg, as well as the 50?

I use mine that way. It works just fine. I know because mine tripped off in Palm Springs when the power got too low and I was plugged in on a 30 amp circuit. (I have a 50 amp unit)

Our 50 amp MH with 50 amp hard wired Progressive Ind. is always connected to 30 (actually 20) amp. service here at home. It works exactly as it should turning off the MH if low volts or a surge is encountered - been there, done that! Obviously a dog bone adapter is required.

You are fine.

Think of it this way. If your 30 amp service "surged" to 50 amps, your rig can handle that.

The surge protector, depending on model and capabilities can do a lot of other stuff that would far exceed your 50 amp capabilities. I have the Progressive Industries hard wired 50 amp protector with remote read out. It keeps me informed on voltage, current and cycles. It protects me from too much juice, too little juice, too fast juice, too slow juice, direct grounds and improperly wired power posts.
