frying pans/ banjos when using SWA

[Maestro]

I was at a site change over on thursday where 7 portakabins where getting removed to make way for 7 new ones each was supplied by a armour cable 3 core cant rememeber the size

each cabin was supplied from a 32A plug to a plastic isolator on the side of the Cabin where LSF glands(no shroud) where used to terminate into the plastic isolators but no flying earth was taken from the gland via a frying pan/ banjo now i need to go back and reconnect up the 7 new cabins i was wondering should i put flying earths on them or not

Depends, does the installation of the cable require the armourings to be earthed?

 

[markc123]

3core...the 3rd core been the earth by any chance?

 

[MDJ]

They may be earthed at the other end

 

[telectrix]

the armour must be earthed, even if not used as cpc.

Even if its 3 core

I would gland it anyway as it is a lot more secure, I don't care if it has a banjo or not but it needs securing in my book

Whys that tel?

 

[markc123]

Whys that tel?

My guess is in case anyone shoves a spade through it, the armoruing will touch the live/neutral and trip it out/blow a fuse.

GN8 also recommends the armouring be connected to earth.

well, think what would be the result if the armour was shorted to the L conductor due to damage and the armour was not earthed. basically, the armour is an exposed conductive part.

 

[markc123]

GN8 also recommends this.

Thought that'd be the reason. I was on the jar's lastnight, heavily lol!

Your too quick tel with the typing

 

[GMES]

As tel says it needs to be earthed at one end to prevent the armouring becoming live

 

[markc123]

Is there an actual reg that decides this, or just good practice as of GN8?

I always earth it anyway. Just asking...

 

[netblindpaul]

Armour MUST be earthed.
Yes there is a reg.
No I'm not going to tell you what it is, IF you come up with some ideas I will consider directing you.
No, I'm not being an arse, if you are not sure, then you need to learn.
It's part of the job.

BTW, I don't particularly care what anyone else thinks of this post, but I'm no longer going to spoon feed people unless they are prepared to at least make an effort themselves.

lol. I do know how the regs work...and yes, i ask to save the time of looking myself.

I won't even ask questions in future. Guessing we all know absolutley everything anyway.

 

[netblindpaul]

Again, another answer, which just re-enforces the reason I post less and less here!

Now that last post was funny, I also gave you a like for good behaviour

With comments like #15 you're not missed.

I've not even disagreed with the fact armour should be earthed. I was asking, where it states it without checking myself.

 

[telectrix]

it says it in Tel's book of electrical rules as writ by me and geordie in 1901, is that good enough?

 

[MDJ]

As I tried to mention earlier perhaps my reply was to short. It is possible the armoured is earthed the other end, if the armoured enters a plastic commando socket then the spark doing the original install may have decided the other end where the cable/ cables enter the DB was the best way to earth, might be worth a look that end to confirm rather than guess.

FFS man, we don't all carry the regs with us 24/7. There's always situations where we scratch our heads a bit, unless of course we're electrical gods

I'd try posting even less if I were you. Mark's post didn't deserve your reply (in my opinion). Daz

 

[trev]

Mark you're obviously clueless mate, best jack it all in. I'll give you £20 for your van and your test gear



Just in case, that was said as a joke.

 

[netblindpaul]

We all scratch our heads on times trev, but, I'm not going to hand stuff on a plate to people who can't be bothered to check things out for themselves.

It is just not going to happen.

IF you're not sure look it up and ask for clarification on your research, giving examples.

IF you are on site, and don't have the book, fine, say so, mind there are ways around that these days, personally if I have my mobile phone I have the regs book, all guidance notes, the OSG, the Pt P book and the design guide at least.
IF I have my iPad, then I have a damn site more also.

IF your Job/Business revolves around these and associated documents then you should have them and access to them at suitable times.

Once you have looked up your questions, post your ideas, then I will be more than willing to help.

If you can't be bothered to check things out then stuff you.

I have already offered him 25 trev lol.

 

[telectrix]

what's up, paul. wrong time of the month? :sailor:

 

[trev]

I have already offered him 25 trev lol.

Dammit, I'll have to go to £30

 

[Maestro]

sorry 1 of the 3 core i being used an earth i would almost definitely say the plug end has not been terminated into a gland i thought at least 1 end had to be to earth even if the sheath is not used as the main earth hence the question just looking for conformation

1 end goes into a 32A plug and the other end is glanded into a plastic isolator(i just took of the isolator when disconeccting the cabins) it was just no frying pans where used on the terminating of the gland

 

[netblindpaul]

Fine, I'll do that, no worries.

It's a shame that in the event of an issue, I can never be the prosecution expert witness against any of you because of this forum.
Lord help you all if I was.

Deal.

Believe me, you're gonna wish you had viewed before purchased lol. M.O.T in April, if it's not near a grand i'll be amazed ha.

 

[trev]

I wasn't going to tell you but the van is worth £40 scrap value. Profit for me

 

[Plonker 3]

Dont forget to drain the fuel first trev, that will be worth even more than that.

 

[trev]

I keep telling you I'm not as daft as I look man

We were taught at college that if the armour is not being used as the earth, then only needs earthing at one end (supply end). If the armour is being used as the earth then it needs to be earthed at both ends.

Literally everything gets left at my back door when i come in from work...and from where im sat now, to the back door is a good 10meters ... far to far with a hangover.

I understand, you're old school. Need not stay away from the forum just because of this thread, as that would be silly.
