Older RVs may have a MagneTek 6300-series converter, a 7300-series power centre, or a later standalone 12V fuse block. The breaker compartment, converter lower section and DC fuse panel are different assemblies. Before replacing a burned or damaged board, find the exact model number on the installed unit and compare the original fuse layout, mounting and wiring.
Three different fuse-panel situations
Older 6345 power centre
Order by exact 6345 model identification. The kit's included board is not automatically a separately stocked FB11.
7300-series converter replacement
Changing a converter is not the same operation as replacing a damaged fuse board.
Separate fuse distribution
A separate part for compatible distribution installations, not a universal 6300- or 7300-series replacement.
What the label and fuse-board arrangement can tell you
| What you find | Relevant part or question | What must be checked |
|---|---|---|
| 6345 printed on original power centre | 6345RU factory converter upgrade kit | Exact 6345 model and kit instructions, including the replacement DC distribution board supplied with the kit |
| 7345 or 7355 printed on lower section | 45RU or 55RU converter-only replacement | Original DC fuse board remains a separate consideration; replace only with an explicitly approved board |
| FB11 printed on standalone fuse panel | Exact Parallax FB11 product | 11 blade-fuse positions, three non-fused positive supply terminals and no included fuses; individual branches limited to 20A DC maximum |
| No legible model label or modified fuse board | Identification not yet confirmed | Full equipment photo, front of the fuse board, enclosure dimensions and any remaining part numbers; do not select by circuit count alone |
On the FB11, the branch circuit terminals are specified for 12–16 AWG conductors and the panel has its own hinged enclosure. The 6345RU upgrade's supplied replacement board serves a particular original power centre. Neither a matching 11-position count nor a similar-looking fuse holder establishes interchangeability.
Compare product images and available RV electrical parts
Start with the FB11 and 6345RU photographs, then compare the individual 45RU and 55RU lower sections. The used 25A converter is included as a separate equipment example, not an asserted substitute. Each link opens its own product details; used parts may be viewed or collected by appointment in Kelowna.
Reference information for older MagneTek panels
Parallax provides a fuse-panel reference, 6345RU product instructions, 45RU reference, 55RU reference, and legacy documentation. Use the exact original model when consulting drawings, not another model within the broad series.
