Hi, I would like to know how I could improve on this board. All opinions

welcome.

 

[Jon Bateson]

If u re read what i put i never say it cant...but simply ones that ive come across that do take the earth through a different entry point they also take the live through a different entry to the neutral. Its all there in my post.

Bit irrelevant then really

521.5.1 Ferromagnetic enclosures: electromagnetic effects
The conductors of an AC circuit installed in a ferromagnetic enclosure shall be arranged so that all line conductors and the neutral conductor, if any, and the appropriate protective conductor are contained within the same enclosure.
Where such conductors enter a ferrous enclosure, they shall be arranged such that the conductors are only collectively surrounded by ferromagnetic material.

Not totally irrelevant @Jon Bateson as some take the above to mean the earth and line conductors should enter at the same point of a DB and there have been a few threads on here regarding this subject where it has been insisted that such must be done in installations by person ordering the work.

Hi - all the above and my things are
- external cabling to CU needs support.
- don’t forget to hoover .

If you are going to quote a reg then at least use the third paragraph

You seem a friendly feller Jon.

I am bud. Didn’t mean to come across any other way but couldn’t understand the post where it was so critical to see how the main earth entered the panel, I could see an aha moment coming up when a lad has put himself in the firing line looking for tips and it would have been irrelevant about the earth. And my point about the ref to regs was valid, don’t quite half a reg to make it fit is all

No, I will quote what I think is appropriate to illustrate what I want to say. You miss the point that it has validity to raise the matter of the earth and line conductors entering the DB in this context.

As you wish

As you wish

I think jon u were waiting for me to slip up so you could jump in to chastise me but now you're going on the defensive because u cant.
It is relevant as like i said in my experience people who take the main earth through a different entry tend to put the live through a different point to the neutral...this is something that shouldnt be done...i was asking where the earth was as to see if this person did the same as to what im used to coming across....ergo totally relevant

 

[The Ghost]

As you wish

I don't need your permission or approval. I have free license without your consent. You again miss the point and fail to redact your previous summary dismissal of a valid point raised by @magnoliafan89. Which there was no need to be so curt and there is a point of discussion that is valid not to be dismissed as you have my making another valid point with "...don't quote half a reg..." You can afford a little more largesse than that surely?

I’m not defensive of anything, I think on the contrary you were waiting to chastise the guy yourself.

When a guy comes on looking for advice and you quote half a regulation to him this could be construed as misleading him into a situation where he thinks he has done wrong. If you had quoted the entire reg this would take away the seed of self doubt that you sowed. I’m not trying to be obnoxious or curt and I sincerely apologise to you and magnolia if that’s how I came across

Chastise what guy, sorry you've lost me there.

Someone has quoted a Regulation number, but has not rewritten the whole Reg in his post, then surely it wouldn't be to much of a problem for the person he was replying to read the entire Regulation, including the third paragraph for themselves, from BS 7671 if of course he has a copy.

 

[The Ghost]

These requirements do not preclude the use of an additional protective conductor in parallel with the steel wire armouring of a cable where such is required to comply with the requirements of the appropriate regulations in Chapters 41 and 54. It is permitted for such an additional protective conductor to enter the ferrous enclosure individually.

There is the other part of the reg.

Show me how the part quoted could lead to confusion of the OP who is clearly competent. Or show how @magnoliafan89 could become confused with or misleading him into confusion. I am not the author of confusion here on the contrary I have been crystal clear. The part quoted from the regs suffices to show that there is a suggestion that all conductors should enter an enclosure with a ferromagnetic component "collectively". Which I take it that @magnoliafan89 was alluding to. Again you miss the point and dismissed as irrelevant that point made by @magnoliafan89 re this matter. To have also inserted the part about an "...additional protective conductor with swa..." does actually muddy the water and could lead to obfuscation of the point clearly made in the "half" of the reg quoted. For illustrative purposes the quote was concise and made the point about conductors entering into an enclosure not being a good idea separately. Whereas you are suggesting it is irrelevant. Herein lies confusion, if you are saying we can discount the implications in that reg while someone is questioning the requirement to do so, then you should quote the reg that says it is irrelevant or acknowledge @magnoliafan89 has a point instead of dismissing his point.
