RIGrunners from West Mountain Radio are great.  I have several of them.  But, I also feel the need to carry a pouch of extra fuses.

I have seen people plug their power source into the wrong end of their RIGrunner…you know the end with the 1 amp fuse, not the one labeled “DCIN” and has the 40 amp fuse.  The first time they power something up the fuse blows.  That sucks.

Recently I became aware of ATC Circuit Breakers from Bussman, or Cooper Industries, or Eaton, whatever they are calling themselves now.

These are small, manual-reset circuit breakers that plug into a standard ATC fuze socket, like the ones found on a RIGrunner.

These circuit breakers are available in 8 different load capacities from 5 to 30 amps.  The specific ratings are 5, 6, 7.5, 10, 15, 20, 25, and 30 amps.  They are colored to match ATC fuses.

You can see these circuit breakers are taller than fuses. For me, this isn’t a problem, but it could be in some installations.



I purchased mine through Amazon, but there are other suppliers.  At the time I purchased they were about $9 each.

More details available from the manufacture at this link:

Powerwerx also has ATC circuit breakers at a much lower price, under $3.  The are available in 10, 15, 20, 25, and 30 amp ratings.  You can get more information here:

I would like to see these in a 40 amp capacity for the DCIN port on the RIGRunner.
