I can't think of any reason why a fuse block would need to be specific to RVs. It's just 12VDC power, as in a car.
I would not use a fuse block designed for the traditional glass-tube (3AG
) fuses, because I greatly prefer to use the plastic-bodied blade-style (ATO
) fuses which have been standard in cars for over two decades. That's a personal preference; some people find it easier to see whether a fuse is blown or not in the glass design, for instance. Blocks for both types of fuses are available from various automotive sources, as well as for the smaller blade-type fuses which are now common (and are too small for my tastes).
My original-equipment Boler
converter has no fuses, and no proper distribution panel: the converter output is wired through three panel-mount circuit breakers
which are mounted through holes in the front panel of the converter.
I like the idea of breakers
, although the ones in my Boler
are annoying in that they have a push-to-reset button, but no way to turn them off like a switch; fuses can be pulled to kill power for troubleshooting or maintenance. Ideally, I would prefer more circuits, and breakers which I can switch; I haven't looked for this type of product yet, since I'll probably keep my original converter as long as it works.
Go-RV / Coast has fuse panels, on the same catalog page
as my breakers, for both styles of fuse: from the brand name, I would guess some of them were designed for marine use. Whatever the source, I would consider whether the cover
(or lack thereof) is appropriate for use in the trailer.
