Question

Guys,
Last night was under the bonnet of my cab, decided it was time to replace the skanky old power cord. Also figured it was time to check out the mains wiring in general
Here is what I found:
- A small metal box, with fuse and power switch
- The Earth was connected to AN INSULATED TERMINAL (so the metal box was not earthed!)
- The Power Switch was only a single pole (not great) but was in the Active Line (good)
- The Fuse was in the Neutral line. I assume this is a BAD THING as it has the potential of the machine being live even with a blown fuse.
Fixes/Changes I made:
- Switch and fuse are now in active line
- Earth terminated properly to metal. Now I have a solid basis to earth the rest of the metalwork in the cab
- New powercord (just buy a good extension lead and cut off the socket end)
- Added a small powerboard to the switched side of the power circuit (in case I ever want to put in a fan, mame or whatever in the future) - this is a reversible change!
What I still need to do:
- Check fuse rating (I am not powering it up at the moment) - whats usual for a standard cab - 120v chassis, peter chou PSU I am guessing a 1.5 - 2A fuse should be OK
- Probably add a line filter
----
It's been said before, I'll say it again - always check your new cab before plugging it in!
Cheers
Jacob
