50 amp surge suppressor, 30 amp rv
I have a 50 amp suppressor from a previous rv. My current rv has 30 amp service. Do I need a new suppressor, or can I use a 50 amp to 30 amp dogbone?

If it is a portable unit... use a pair of dogbones.. (one 30-50 one 50-30) and not only will it work,,, perfectly... but these devices serve multiple functions.
ONE is spike supression (Fast short transint high voltage) and the 50 amp unit (when used on a 30 amp circuit) is far far better at this than the 30 amp unit is.
If it is a hard wired......
You have two legs.. Bridge them,, The current sensors,, Put 'em both on the combined wire.. It will still work just like the above.
This IS NOT A GOOD IDEA on our last outing, there were no 50 amp plugs, only 30; so, I plugged the 30 amp male to 50 amp femail dogbone into the 30 amp plug; the 50 amp Progressive industries surge-protector was plugged into the femail side of the 30 amp to 50 amp dog-bone; our 30 amp trailer cable was plugged into this. It all worked fine for about 4 or 5 hours, then the power went out. One of the dog bones femail plugs were fried to a crisp. We purchased a 30 amp power protector this week: lesson learned.
