 |
|
Is it normal for the master relay to be connected directly to ground via the master On switch? In the circuit recommended by Vans, which is probably an aviation standard design, there is no fuse or circuit breaker in series with the current flowing through the Master relay coil.
Every other circuit seems to have a protection device wired in series.
Perhaps someone could explain why?

The fuse or CB protects the wire against overheating due to excessive
current intensity. In this particular circuit, the current is limited by
the relay coil, so no protection is needed.
Hope this helps,
