Question:
I’m doing a remodel and don’t care about matching the original cutout. How do I choose between the PM47VR, PM67VR, and PM77VR?
asked by: Ethan
Expert Reply:
Ethan, if you’re not constrained by the original cutout, the decision really comes down to shore power rating and battery needs.
-Choose the # PM47VR if you’re on 30-amp service with light duty 12V loads (12v led lights, fan etc.)
-Step up to the # PM67VR if you’re still on 30-amp service but want stronger battery charging or power for more accessories.
-Go with the # PM77VR if your RV or build uses 50-amp service and you want higher capacity plus modern features like wireless control.
All three are full AC/DC power centers with breaker slots, fuse slots, and charging built in - so the best choice is the one that matches how you plan to use power.
What shore power setup are you planning to run? 30A or 50A?
