bgu design

[Lc85]

I have the attached design for BGU's (all in parallel) but I cant work out how to practically wire a 4 core cable between the two BGU's. Can anyone offer some guidance please.

Thanks

Nothing attached. I've checked with two different browsers.

Now attached, sorry.

Ah, BGU is "Break Glass Unit". I couldn't derive that from the original post.

Not my area.

Standby for others to chime in.

I don't know what is worse:
TLAs or TLAs but I seem to have more trouble with Two Letter Acronyms than with TLAs.

TLA's often leave me SSU [ that's seriously screwed up, not Saybolt seconds universal] . . .

@Lc85 How are the BGUs supposed to operate? Your diagram is not understandable to me. Are the BGUs basically switches? Aren't they just wired in series?

Of course I can. I can do anything. I can do absolutely anything. I'm an expert!

IRstuff,
The BGU's are wired in parallel. My question was just about the wiring between two break glass units as I am not sure that the BGU's will have enough terminals.

Thanks

?? Are you sure? That seems different that how other people do it:
