Looking for advice with a self made c/u

[martinh89]

Afternoon, I've spent the day looking for an ip55 or above 6way single phase c/u... Its to be installed inside an enw substation and from past experience they don't expect the metal enclosed c/u, so long story cut short, I've got an ip65 enclosure with dim rail but I'm not sure how to fit a neutral and earth bar as its not come with them.. .. Any advice would be much appreciated

Here's something to look at .
6 Way Consumer Unit - Weathertight - Super Garage Kit 1 x 63A RCD + 6 MCBs - https://www.tlc-direct.co.uk/Products/MK5704SSP1.html?source=adwords&ad_position=&ad_id=315107931576&placement=&kw=&network=u&matchtype=&ad_type=&product_id=MK5704SSP1&product_partition_id=576185600782&version=finalurl_v3&gclid=EAIaIQobChMIqYekzr_F4AIV7RDTCh3OmAwfEAQYAiABEgLClfD_BwE

That would be perfect however I'm doing the install tomorrow... It should never really have been left for me to order but I got it dumped on me this morning ... I think I've resolved it anyway, I've taken a neutral and earth bar out of an old c/u and attached one to either side of the box with a roofing bolt and nut

 

[martinh89]

Also I've just checked branch finder... I'm working in Cumbria tomorrow the closest one was Luton

Do you not have to have some form of ‘certfication’ (not quite the right term) to produce or provide such a product?

I was just thinking the very same.

 

[telectrix]

@OP.ask your boss to sort out CE approval, or wait till March 30th.

 

[martinh89]

Yes that's a very good point ,I'll install it tomorrow but I've ordered the above link, so if something comes back should be an easy change

 

[martinh89]

The long bar is offset because the terminal hole was larger than the others so the roofing bolt would fit through without drilling the hole

 

[telectrix]

Irwin drill bits, and a Bahco adjustable. ... show off. .

But don't you have en externally exposed bolt head connected to neutral?

useful test point, or bit of gaffer tape will sort out.

Yes I'm hopeing to cover it or failing that I'll remove it and just leave it inside loose, not ideal

To be fair that sounds poor.

Nylon nut and bolt?

Nylon nut and bolt?

Just trying to find that now locally

 

[Moley]

I've got a bag full in the back of my van.

How does this work out with the “same make if breakers in the same make of board” regulation?

I assume you've never worked at a power station or sub. There are no regulations!

I have actually considering I work for the electricity network... Clearly you haven't because any dno set out the standard regs plus there own twist ie ip ratings ect..

I think he was replying to littlespark's comment.

All my work is at power stations and occasionally subs but I'm normally on HV/EHV with transformers and switchgear. I should have put a on my last post as I've seen some of the work on sites that certainly wouldn't come up to current, or for that matter, previous regs. Some of it is quite new install stuff too. Not by me I should add

 

[Moley]

Yup, I wasn't refering to your work

 

[martinh89]

Fair enough, thought there was a snide comment there ..... I work in power stations and subs lv and hv, I do the lv terms, hv terms and small wiring ... I work under enw, ukpn npg and wpd and all have had different spec

 

[Moley]

No, not directed at your work at all. It was towards the normal 'standard' of site engineer installed equipment. I've yet to come across a site engineer who has any 'normal' electrical qualifications. Most of them would believe you if you told them the 14th edition was the latest release

 

[telectrix]

blank grommet stuck on with gorilla snot glue?

 

[johnduffell]

Just put the whole thing inside a bigger enclosure

 

[martinh89]

I've found a cpc on route tomorrow that have 4mm plastic bolts... Going to put them in...... Lesson learnt though, not ordering materials for a supervisor last minute ever again

 

[shaun1]

Might be a bit late for this one but you could use some din rail terminal strip for a neutral bar (if you have the space to fit it somewhere without it being exposed on the front cutout)

 

[freddo]

All that effort messing about with neutral bars when you could have just stuffed all the circuit neutrals together into the RCDs load side neutral terminal!

 

[martinh89]

Bit of an up date..... So after arriving on site and speaking to the foreman I discovered that I'm the first person to attend site from the electrical department . .. . Long story cut short, the lv panel came already fitted with a bulkhead and an rcd protected socket, so no need for any small wiring and botched consumer unit did this instead

[DPG]

Blimy that was a few wasted hours then - are they paying you for that?

 

[martinh89]

Yep... I get day rate upto 10 hours and time and half after so there definitely getting a bill

Correct rough ad

Rough as a badgers
