Ok, they really do not have an electrical code here, but I just have to share this stuff with somebody who understands, I have a ton of them but will just send 2 for now.

EWWW!!!!

Was that splice in picture #2 really coated with "hot melt" glue??????

Or what is that gooey-looking stuff?

The best part of the transfer switch is how the green/yellow wire is so neatly taped off.

Ditto about the ground in the xfer switch... Those conductors seem a little on the light side for 800A [Linked Image]

Tell me if I'm seeing this right... Did someone come across that burnt connection in the 2nd pic and just cover it with some hot glue???? Are wirenuts or choc-blocks or whatever you guys use getting scarce?

BTW, Welcome to ECN Roger [Linked Image]

I want to say that the "hot glue" is actually the remains of a "choc block" (euro style barrier strip.. note the brass screw near the red wire in the lower part of the blob.

Pic #1: Those wires are rated for 800 amps?

I don't think so...

Pic #2: It looks like there weren't any wirenuts in the vicinity when this box was made up. Did they use wax instead?

That has got to be a nightmare to go to another country and figure out their electrical code, or lackthereof. What I mean is learning the color coordination of conductors in another country, like Afghanistan, has got to be a PITA.

The second picture of the junction box is a "survivor" another one close by actually caught fire, good thing it was during the day so we were able to put the fire out and had minimal damage to the structure. This one was really close to going into flames as well, we have since disconnected all the exhaust fans and are trying to get some listed components to do the repairs.

Most of the components available here are either made in Iran or Pakistan, some kind of rubber insulation on the wire and of course no markings at all.

Recip's are European in design and made who knows where.

I have been here 6 months now and are finally getting some good stuff shipped in from the states. Our site is supplied by generator power only. We are on a contract that installs armor on wheeled vehicles for use in the Middle East.

I will submit 2 more pictures.

I see melted connectors in light fittings here quite regularly, where someone has not realized that they won't stand up to the heat. I've seen some in which the plastic is just a blob and the metal connector is completely bare.

Here's what the blocks look like before they melt:

(Named "Choc Blocks" because in the "old days" they were commonly a dark brown chocolate color -- And were much heavier and more tolerant of heat too.)

Looks like normal British colors: Red/yellow/blue for A/B/C phases respectively, black neutral. At least the colors are all there, but bearing in mind that sometime last year there was that pic from Iraq where they'd used black as a phase and one of the other colors as neutral, maybe this is anybody's guess.

If the rest of wiring is like the junciton for the fan, it would probably be redundant anyway. It doesn't look like they've run any earth (grounding) wires in the conduit.
