no.....The type of power systems you will encounter in theatrewill be safe (ish) to absolute death traps and because no-one has died theywill be kept !
4 wire (TN-C) is banned by Task Force Power but you willcome across it. Same as TT not allowed but its here.
4&5 (TN-C-S) wire will be the main type but they willbe riddle with N-E bonds fitted randomly in MDP's (Main Distribution Panel's),SDP's (Sub-...) and CDP's. They system will also revert between 4-5-5-4-5-4-...etc producing 'Objectionable' current in EGC (Equipment Grounding Conductors)/CPC's, conduit (pipe). watch out for N bars screwed to the panel with noinsulation (back to a 4wire) and bolted to a metal skinned building.
All new electrical Systems are to be 5wire (TN-S) TFPowerdirective as they are easier to understand and follow.
Transfer switches will be 3pole or 4pole. 3pole T/S areto have only one genny N-E bonded. 4pole, both gennys are to be N-E bonded.
Cable on nearly every distribution system will have beenwhat was around at the time so you'll have 4c rubber in the ground no ductingand about 4-6inch below the hard core. But mostly it will be surface laid evenacross roads with some sand bags on top (if you’re lucky).
Most MCB's will be massively over rated e.g. found a3500A feeding a 120mm 4c SWA other end was a 500A though, so that was better!!!!
Lots of cables will have been given a haircut to get themto fit into breakers, bars, lugs etc
SWA will have been cut with only 10-30% captured andrammed into the earth bar. Split bolt repair is approved.
Earth spike are routinely cut off so a 10foot rod mayonly be 4foot and that’s all a 750KVA genny will have
A cable will start of as a 5c SWA and pop out the groundas a 4c SOOW, so be warned.
120/240V MCB's means they can have 240 3phase in them butcan't be fitted to 230/400v boards but they are.
Boards will be rated to 240V/277V but will have 380-440Vin them.
Ip rating is NEMA. kit should be IP54 min (3R) but isn't.Usual thing is build a cupboard round it.
Guards will be missing in most boards and homemade panelswith live Buss bars open to touch are common.
Gland plates are an optional extra for SWA but as mostSWA isn't glanded off there is no need for them!! So just let the weight of thecable hang from the terminal of the breaker and as there is no gland platethere will be plenty of air to stop the MCB overheating.
Air temp is 50degrees C ground temp is 35 if you botherto do any calc's.
Systems may have been put in for 60Hz 120v kit and todaysgenny is 50Hz220-250v so watch out the amount of kit that gets fried as thewrong voltage is coming out of the socket.
Never come across a frequency converter loads of trannysthough from 50w plug in to 'massive'!
The above are all facts given tongue in cheek.
If you’re here closing down camps buy a solar shower asthere will be no grey water recovery toward the end and LSS units will havegone too. So get use to the idea of dropping a 'Richard the 3rd' in to a bag.
Tony. I never said it was acceptable its what happensthough.
I never said or implied I have a vast knowledge ofanything. But I hope the above helps out someone.
RE = Royal Engineers, so you were part right it doesn'tstand for Real Engineers, but we are in every way and every day.
Your right he doesn’t say he is coming out here but I'dsay it was implied as "95% sure I'm got a start on the troop withdrawalcontract" and asking about electrical in Afghanistan. I may be wrongthough on that.
Glennspark, What? You the sites Internetshire enforcer?
just a fella.....
who got a bit browned off when you gave a very respected member in here a load of verbal diarrhea
