Author Topic: Correct type replacement fuse  (Read 2686 times)

One fuse blew on my Icom 208H power lead ( I tried to attach something else other than the radio to the connector and it failed).
The 2018H manual states on page 76 that the replacement fuse should be a FGB 20 A.
My question is this - what is FGB ? I found 20 A fuses at the local automotive shops type SFE, but no one could tell me what SFE, much less FGB, stood for.
On-line searches were fruitless, too.
Is the FGB a special type of fuse or can I simply substitute the readily available 20 A SFE types?

Thank you for the link - I agree it's an interesting read about fuses, but I didn't see anything that answers my specific questions:
I am using the OEM ICOM power cable and fuses attached to my car battery -  all I need to understand is what is the correct replacement fuse for the one that blew?  The automotive shops and Radio Shack stock the 20 A SFE fuses - but no one has or even knows what a 20A FGB fuse is.

Use a 20A fast-blow glass fuse of the appropriate length. That's what I use in all my radios, fused on both the pos and neg leads.

Well that's weird. W9MMS's response wasn't there when I replied. Well 2 heads are better than 1, eh? :-)
