 |
|
I am in the designing stage for a new electrical system for my Rotax 912S powered Europa and am using Z16 as the basis. By now I have a pretty thorough understanding of the philosophy of Z16, but one question keeps popping up in my mind:
Why is the positive side of the crowbar OV module connected to the 'downstream side' of the master switch?
In my reasoning I believe it to be more robust to connect the positive side of the OV module to the downstream side of the 5A C/B. This would take the master switch and the wire between C/B and master switch out as potential points of failure during an O/V situation:
Master Bus -> Fuselink > 18AWG wire > to C/B
Then run 2 circuits from this C/B:
(1) --> to OV Module
(2) --> 22AWG wire > to Master Switch
I know this would be a small amount of additional protection for a situation that is likely to be very rare, but it's a very minor and easy change to Z16.
So basically what I would like to know: is there any reason why I should not connect it like this?
