Hi All

I want to install two cigar lighter power supplies in the instrument panel.

Usage will mainly be to charge my iPad and Phone, or maybe other things.

I was planing to run a cable (aircraft cable ??? watts)  directly from the Battery + and return to the Battery - with an in-line fuse, Amps ???

The Battery is located in the rear fuselage .

Any Comments or Help.



Alan

Hi Alan,



Although your plan would work it is not the best arrangement.  On most

Europas there will be a positive supply electrical bus bar somewhere behind

the instrument panel that is controlled by a battery master switch. It would

be better to take a connection from there and use a panel mounted fuse or

circuit breaker to protect the wiring to the cigar lighter sockets.  You

should also be able to find a negative bus bar or connection stud behind the

panel. The size of the cable and then the size of the fuse/ circuit breaker

will be determined by what you intend to connect to the sockets.  If you are

not going to take more than 5amps you could use 22 gauge wire and a five amp

fuse. As you are planning to have two sockets it is probably best to use 20

gauge and maybe a 7 or 10 amp fuse.



It is important to be able to disconnect all electrical supplies in an

emergency so it is not good practice to connect things directly to the

battery.



Regards



Brian Davies

Morning Alan



When you take the panel out you should find a power and negative bus in the

back fed directly from the battery.  I suggest you take the power from that

via a CB.  Trouble with in line fuses in the back of the panel is that it

makes a big job just to change a fuse unless you have easy access. 



Regards



Pete

Good Morning to you Both.

Yes , that all makes good sense, and that,s what i will do.

I was a bit reluctant about going in behind the panel, but hopefully i will be able to do it.

The making the new little panel plate and fixing i can manage ok.

I will make sure i use a good crimping tool, will post a photo when finished, but allow up to six weeks.

Ps, Would like to find the approx 1/2"x1/2" square black push button CB to match the ones i have, ?? have not seen any yet.

Regards

Alan

Alan,



Europa used to stock them- worth a try.  They are also sold by RS  (ETA 1100

series).
