Timmyb Posted December 15, 2020 Share Posted December 15, 2020 Hi everybody, hope all is well. I’m replacing the dash in my old Mack. Doing a clean up of wiring and replacing a few other things while there. I am after some circuit breakers to suit an Aussie R model, perhaps they were the same as the US ones? Alternatively have any of you changed to a different type? Any help is appreciated. Quote Link to comment Share on other sites More sharing options...
alex g Posted December 15, 2020 Share Posted December 15, 2020 Those look different than mine. I don't have a pic at this time. Quote Link to comment Share on other sites More sharing options...
Timmyb Posted December 16, 2020 Author Share Posted December 16, 2020 Thanks Alex, I was hoping these parts might of been available over there. Seems most guys in Australia just ditch them and run a fuse box when they are doing an in depth restoration. Thanks again mate. Quote Link to comment Share on other sites More sharing options...
mrsmackpaul Posted December 16, 2020 Share Posted December 16, 2020 Mine are nothing like that at all and mine all look original So no help from me, I would if you can, take one out and it most likely has the manufacturers name and model number If you do, bung a photo up and we can take it from there Paul Quote Link to comment Share on other sites More sharing options...
Timmyb Posted December 16, 2020 Author Share Posted December 16, 2020 Paul, they are Westinghouse HBR N28 circuit breakers. I’ve got a line on some 2nd hand ones. Interesting that yours are different. On my old man Valueliner he has the same ones only a couple of extra ones. Quote Link to comment Share on other sites More sharing options...
Hayseed Posted December 16, 2020 Share Posted December 16, 2020 They Look nothing Like what My old F model had either Timmy..! Pure W.A.G. But check out Jaycar, they have all sorts of Odd stuff..

Westinghouse are now Eaton brand, so that might be a place to start Paul Quote Link to comment Share on other sites More sharing options...

Someone hypothesised that this type might have been used in fuel trucks. Im not sure, but the spare ones I found were out of an old shell truck, and mine was a shell truck also. Something to ponder anyway. 1 Quote Link to comment Share on other sites More sharing options...
mrsmackpaul Posted December 21, 2020 Share Posted December 21, 2020 (edited) Could well of been, "intrinsically safe" is proper name, in other words, explosion proof or spark proof If it failed it wouldn't cause a spark Australian fuel trucks were generally very lightly specced, so if it has 34 ass end or something along those lines and is single rail it probably was a fuel truck There are no doubt other tell tale signs if you new the right person to ask As I understand it each fuel company had their own specific requirements and I feel these even varied from state to state So if you new the right person to ask you could probably narrow it right down quite easily Paul Edited December 21, 2020 by mrsmackpaul Quote Link to comment Share on other sites More sharing options...
Timmyb Posted December 23, 2020 Author Share Posted December 23, 2020 The plot thickens, turns out they are actually AC breakers. Had 2 mates confirm that for me. Yeah mine came out with 34’s and short wheelbase and single rail. All of that has been changed in the 36 years it’s been alive. it also has an emergency shut off button, which activates the engine brakes to kill the engine. As well as the shell colours under the door rubbers. Quote Link to comment Share on other sites More sharing options...
mrsmackpaul Posted December 23, 2020 Share Posted December 23, 2020 Yes they do look like a biscuit breaker, or very similar to them I have some biscuit breakers that are slightly different, give me a few days (around 10 or so) when I get home after Chrissy and I'll have a measure Paul Quote Link to comment Share on other sites More sharing options...
