Paul, MEM still have a headquarters in B/Ham Uk. However they are now owned by The Eaton Corporation who i am sure our American friends will know only to well.

Randy,
The control wires are all yellow and they carry 230V, although in pics 3 & 4 they look grey because of UV damage from the sun.
This wiring was originally run through the first lot of flexible PVC ever made here and it's resistance to UV damage was rather poor.
Doug,
Most of our Control circuits in Industrial places are either 230V or 400VAC.
In the actual slaughter area of the plant, the machines are controlled by either air actuated switches and the contactor and so forth is installed in the roof void above the machine.
Paul,
The porcelain fuses on the top panel are illegal here now and even so it has always been illegal to install these types of fuses in a side-by-side pattern, where there is 400V between the seperate fuses.
As a note, I'm told that this panel is going to be ripped out and replaced "sometime in the future".
I just hope that I don't get given that job.
The reason?, If you look closely at the top of the panel, on each side of the Main Isolator, you'll see a row of small Mineral insulated cables entering the panel.
I hate this type of cable with a passion, it's so hard to work with and it can give you some nasty suprises.
Any new panel will have to take these cables into account, as well.
I just hope that it gets done while I'm on holiday one day.

Mike, So it's fair to say you're not too bothered by blood and guts then?

Here's some other pics of the same Plant room, that I "found", when I was cleaning out my Computer yesterday.



Fire Alarm wires in Flexible PVC conduit.



Fire Alarm, 400V, 230V and 24V wires all mixed up!



Same wires, but there are also Emergency lighting circuits and a few others in there too.
