Question:
My older Progressive Dynamics panel is starting to act up. Can I switch to one of these WFCO panels even if its not the same brand? 30A shore hookup.

Hey Jeff - yes, you absolutely can switch brands as long as you match the service rating and verify the cutout size so you don't have to make big changes to the cutout (trimming or filling a gap).
All three of these models you were looking at - # WF46FR 40A horizontal, # WF86FR 55A horizontal, and # WFC72GR 40A vertical - are designed for standard 30A shore power setups. Not the heavier duty 50A found in bigger RVs.
I recommend checking your cabinet opening size and orientation so you don't pick one that requires lots of custom work.
Here are the cutout requirements:
- # WF46FR: 10-3/8 inch wide x 4-1/8 inch deep x 7 inch tall
- # WF86FR: 12-3/16" wide x 11" tall.
- # WFC72GR vertical: 7-13/16 inch wide x 7-3/8 inch deep x 11-5/16 inch tall
Do you know the dimensions of your existing cutout?
