Hi Guys
I have a P+B pull able breaker I want to use as my E-Bus feed.
I ordered a small clip from Spruce used for that purpose, but I guess it
is for a Klixon breaker, it's too large in diameter and not wide enough
for a P+B pull able breaker.
Anyone have any suggestions?
I cut a blue translucent piece of polyurethane fuel line to length, then
slit it. It kinda works, but I have a suspicion someone has figured a
better way.

I'm having trouble visualizing your design goal. Are you
talking about a "circuit breaker lock"?
http://www.aircraftspruce.com/catalog/elpages/edmobreakerlocks.php
I presume you're talking about the alternate feed path
to the e-bus. What is the value in putting a breaker on
the panel for this function as opposed to a switch? Do you
plan to pre-flight check this path? Is there also wire
protection on this path located right at the battery
bus? Does not a little piece of plastic become a problematic
cockpit accessory like loose fuses, AA batteries, pencils,
pistachio shells and Hershey's kisses?

Hi Bob
Thx. for the reply.
I am building a Europa monowheel with a electrical dependent Rotax 914.
Battery is aft. I have a Flaming River battery contactor on the passenger
headrest to be used as main battery contactor.
I have panel laid out to my liking, and besides the fact that there is
precious little panel space I do not like a cluttered panel with stuff
that could be situated elsewhere. :
http://www.europaowners.org/modules.php?set_albumName=album211&op=modload&name=gallery&file=index&include=view_album.php
Thus it was my choice to make in and aft of passenger headrest an
electrical center. Space is precious and the aft section of headrest
mounted on the aluminium panel has 6 pullable circuit breakers and 3
circuit breaker/switches. :
http://www.europaowners.org/modules.php?set_albumName=album261&op=modload&name=gallery&file=index&include=view_album.php
Wire run from Battery switch to aft Bus is inches. Buss run to Shotky
diode from battery switch is inches. Shotky Diode wire run to E-Buss
alternate feed P+B pullable Breaker/Switch is inches.
Aft buss, E-Buss and always hot buss are located on P+B
Breakers/Breaker/Switches fabricated from .025" copper ~ 3/8" wide. Yes
all wires are protected except for the short run from battery contactor.
My always hot buss consists of only two things, pitch trim on a 1 amp
pullable breaker and E-Buss alternate feed pullable breaker. It is the
E-Buss alternate feed pullable breaker I wish to keep "pulled". I am
afraid it could be accidental pushed in when flipping on and off 3
Breaker/Switches, which would kill my battery if I walked away from plane
with it closed. My E-Buss consists of fuel pump #2, Rotax 914 TCU and
Airmaster CS Propeller controller.
The link included in your E-Mail from ACS is the exact breaker clip I
have, but it is not designed for a P+B pullable breaker. The E-buss
alternate feed is not something that will get much use, but if I need it,
just smack the Flaming River main switch, push E-buss alternate feed and
turn on pump #2. I don't like having stuff floating around cockpit, thus
for this situation if I were to use my tube, would use a piece of Spectra
to teather it. BTW Spectra is incredibly strong fishing line.
Would be nice to have something like a sliding lock.
I could invent something if i need to, but am hoping someone else figured
out a reasonable solution.
It just so happens my basement computer is on the light switch near the
top of the steps. Got to be a pain when family would go upstairs and leave
me in the dark, but worst they turned off computer. I fabricated a gizmo
that lived on the switch plate attachment screw with just the right amount
of "wiggulation" and it was put under switch so you couldn't turn it off
without a bit of effort. Worked and still works great. Took me way over an
hour to fabricate and get it tweaked. A few weeks later I saw essential
the same thing in hardware store for under a buck.
Anyway any ideas?
Thx.
Sincerely
Ron Parigoris

Hi Ron,
Thanks for providing some low cost options during these trying financial times. I also enjoyed the humor in the descriptions on your site! Thanks for letting me enjoy your work. Earl
