Eric,

Take a look at this thread to see what can go wrong:

I might be missing something here, but it seems that unlike the Z13/8, if the battery contactor is open, only the battery bus will be fed by the aux alt (no feed for equipment that might be on a tradi ...

John,

It looks like you are going to change course here based on Bob's advice, so this information may not be needed but, I noticed yesterday that SteinAir is selling bus bar/terminal strips with 1 ...

This is the Bussman 15710 Series ATC Fuse Block, which includes the 15711, 15712 and 15713 (single, dual and triple bus versions).

The tool is for the Delphi Pack-Conn III terminals that are insert ...

>Very easy to make from a piece of ~.030-.040 thick steel.

Chris,

This means the dimension of 0.40 on the drawing should be 0.04?

Jef,

You can order these over the internet in a variety of configurations from:

Search for 15711 and 15712 to see the variety of single and dual bus configurations. ...

Just to play the Devil's advocate:

The breaker is part of an overvoltage protection circuit, not a conventional B lead breaker prone to nuisance popping. Why would anyone be resetting this breaker ...

Some of you toiling to understand the whys and wherefores of the Z diagrams might also enjoy this bit of silliness:

Switch breakers will function for this application.

I have read conflicting reports about the long term reliability of these. Some folks end up tearing them out because they don't hold up and othe ...

Noah,

If you use an LR3C instead of the SB1B, the normal operating condition would be with the Aux alternator and alt battery feed off. You would be feeding the E-bus through the diode under norma ...

Noah,

I don't see any wiring errors.

I am planning to use the same architecture but with a couple of different details you might consider.

1. I am going to eliminate the two shunts and run bo ...

Bob,

Am I correct in thinking that in the rare "shorted alternator diode" scenario, the alternator is providing a low resistance path to ground and the power source that the big breaker o ...

As a follow up: the 5 amp breaker protects against overvoltage as part of the crowbar circuit. If overvoltage is detected by the regulator, the breaker is shorted to ground, trips and interrupts the ...

James,

The 5 amp breaker in the line controlling the regulator is for overvoltage protection, assuming you are using a B&C or PlanePower regulator for an externally regulated alternator or are ...

James,

The fuseable link is to protect the wire between the bus and the breaker. The breaker is there as part of the overvoltage protection circuit. If you get an overvoltage event, you want the ...

David,

Regarding your schematic, If you are planning to run a heavily loaded e-bus (yours is fused for 15 amps), I think you are going to want to use the heavy duty e-bus switching with a relay (Z- ...

Noah,

In another thread earlier this weekend I proposed the use of a second, parallel master contactor in Z-12 instead of an E-bus to accomplish what you are looking for. This would give you the p ...

In "A Short Discussion of the Endurance Bus" on page Z-2 of Rev 12A of The AeroElectric Connection it states that "Unless you're planning TWO alternators (Z-12, Z-13 or Z-14) then the p ...

If I understand your system, you have a circuit from the battery straight to the starter contactor.

Running the starter contactor in series with the master bus contactor allows you to kill the s ...

Hi Bill,

Just curious: Why have you wired SW01 and SW02 to disconnect both the alternator and battery at the same time instead of using the progressive transfer scheme in most of the Z diagrams?
