 Posted: Sun Feb 28, 2021 5:36 pm Post subject: Fuse Block - Breaker Combination |
 |
|
RV-7 project, deep into the wiring, basically a Z101 architecture.
Fuse blocks are used for the main bus and clearance delivery bus but I do have a few breakers. Flap, trim and auto pilot breakers located near the fuse blocks. The field breaker is next tho the master switch.
My question is: Do I protect the 12AWG wire going from the main fuse block stud to the breaker copper bus bar.
It would seem to me, to be considered part of the fat wire coming from the master contactor but I'm unsure hence the post.
The field breaker will get a fusible link, so I'm covered there.

It depends. Is the wire only a few inches long? Is it well supported so that
even if a terminal breaks, the wire will not fall? If that wire has mechanical
protection, then electrical protection is not necessary.
