[RE-wrenches] 48 VDC Control fusing

[Jeff Clearwater]

Hi Drake,

Some in-line glass fuses and holders are not rated for 48 VDC.  The 
midnite 1 Amp breaker is an good option like Ray said but sometimes I 
prefer to use a fuse so it doesn't get accidentally shut off or so I can 
bury it behind a panel so the customer doesn't have too easy access.

So If I have easy access to a place to mount DIN Rail such as in a 
Midnite E-Panel - then I use a midnite touch-fuse holder 
<https://www.solar-electric.com/mnts.html?gclid=Cj0KCQiAkePyBRCEARIsAMy5Scu3bFcDAmHic0cs474Z2qnMm2p9nBF_8QvdPVIHMsSTTbha6YxfoSAaApauEALw_wcB> 
and a 1 amp fuse.  Or you can get them at any supply house like this.

And of course it's easy enough to add a piece of DIN Rail to the back of 
any panel.

I like using this approach for fusing 24 V power supplies running the 
monitoring equipment too - again so they don't get easily shut off.

Hope that helps.

Best,

Jeff
