Re: Crowbar installation

[John Cliff <john@crixbinfield.freeserve.co.uk>]

For those people who don't frequent the Aeroelectric list, Bob Nuckolls has
reported that his crowbar units suffer from very occasional nuisance trips in
some aircraft.  This is why, I think, he recommends use of an accessible c/b
with it, rather than a fuse, which he normally prefers.  He also suggests
testing the crowbar (by creating an overvoltage by means of your choice) on
installation and annually thereafter.
