Recommendations for metal cable fixings

[Gavin John Hyde]

I am planning a job in Bath for an EV Charger on a Grade 1 listed building.
Have a long cable run at height, planning dept have raised issues with cable cleats! feel they are a bit chunky and would prefer something with a less chunky profile!! given they are nearly 2 and half stories up from ground nobody is going to notice! but the planning guy is a pedantic so and so.
Have also stipulated that cable and fixings must be painted on completion to blend in with Bath stone.
Owing to the length of cable run I will be using H07RNF - lighter and easier to work with up the scaffolding than SWA. Customer doesn't mind cost.
Only low profile option I can think of is metal cable ties and bases. base screwed to wall then tie cable. paint on completion.
If I used metal buckle clips then they are a bit fiddly to work with on larger cables.
Any other suggestions?

There are lots of cable support options about now thanks to reg changes, these are fairly unobtrusive. Electric Centre catalogue also has them.

Aren't they just P clips?

 

[Gavin John Hyde]

I didn't consider metal p clips as I haven't used them on anything larger than 2.5mm flex. I am using 10mm 3 core H07 so will go and have a look at the options

 

[Dustydazzler]

If the cable in its entirety is to be painted in then I would just use 'white' Pclips plugged and screwed

They are indeed.

Have you considered hituff/NYYJ cable as an alternative to H07RNF?

 

[Midwest]

More interested on how your going to paint the H07RNF?

Once its on the wall the customer is going to paint it, hes a funny guy. extremely intelligent and wealthy but wants me to do electrics then as he likes to dabble in a bit of watercolor and oil painting in his spare time has decided he wants to paint it himself.
He will have scaffolding up to get up so no problem for him.
council have specified the paint type, make and colour as part of palnning

Considered a lot of options for the cable but due to several awkward spots in routing cable behind or around things opted for H07 due to its more pliable qualities. SWA would have been a right ball ache even if cheaper.

Clear p clips would do the job

 

[Midwest]

I'm not aware of any paint, that would adhere to rubber, over time at least?

Edit; I've just googled, and see you can. But I'm not convinced.

 

[h901]

Or you could use these

 

[SparkySy]

h901 I've used those before with wall dogs for a 6mm 3c H07 and steel ties, worked well and looked neat can't fault them!

 

[SparkyChick]

You could also check out the Linian Fire Clips... drill the right size hole, put onto the cable and push into the hole and they are done. Come in a variety of sizes and colours.

 

[telectrix]

2nd for the Linian. pricey but time saving.

 

[Rigpig]

3rd for linian. Slim profile. Very quick to install. Eye wateringly expensive....

 

[suffolkspark]

Guess they're gonna have to be fairly frequent along the length, I know its 10mm 3c but that ho7 is a bit saggy

 

[Devonchris]

I'm surprised the planners didn't go with black conduit. Make it look like drain pipes, there are loads of them on those grade 1 buildings. Even Jane Austin centre and Great Pulteney Street.

 

[AJshep]

I would also go for linian think the ones you need for swa are called "Linian super clips" the cost will probably be saved in labour.

 

[telectrix]

whynot use MICC. plain copper with copper p clips. looks great on old buildings.

The OD is also a lot smaller.

Any paint on any cable type is going to look gash in a few years probably worse than plan old cable.

 

[freddo]

Edit: It will also need less fixings and be easier to paint if needed.

Never seen those Linian clips before...thanks guys!
I love new stuff...

Go back to the planning arsetrumpet and get them to tell you exactly what they want you to use, otherwise they're just going "no guv, you can't use them ugly clips and plain cable, you must paint the cable the colour of the clouds and it must be secured with pixie tears from a thousand ground up pixies, oh yea and don't forget to comply with 7671 but the pixie tears MUST be used....and we're not going to tell you where the pixies are!"....cue them girlishly sniggering and skipping off to see the sherbet king atop gumdrop mountain

Nah just get tiresome of half information, like when the wife says get me a drink so I get the drink and go to give it to her (placed in hand so you know, she can drink it) only to get "put it on the table then"....if that's what you wanted WHY DIDNT YOU BLOODY SAY SO! ?

ANYWAY divergence over ?

With practice, you can get it the other way round.

 

[richy3333]

Another vote for Linian clips. We really like them and no need for plugs and screws

I tried to buy some P clips in my local wholesaler the other week.... they looked at me as if I had horns coming out of my head and 3 eyes !

 

[Lister1987]

Ain't that the truth, and yet they have the cheek to come to us when something has moved (read: put away) and ask where we put X item.....you're the woman that never forgets, you tell me where it usually lives...

years ago, i had 3 cheques from customers totalling a few hundred. put them on hall table ready to take to bank. went out in a rush, left them there. 7 months later found them in a drawer "tidied up". 'er indoors swears she never touched 'em. had to take them all back to each customer and get them to issue new cheques.

Tel, I know we have gone off-topic but...
a few years ago my Mum sent me to the bank to pay in 3 cheques for her. The girl took them, then scrabbled about in some drawers (no, not hers!) for a couple of minutes and said "Sorry, i can't find a calculator!" What??? In a bank??? So i said, gimme a pen and a bit of paper which she did, i added them up, she took the paper and just accepted the total and credited the account. As I turned to go she said "Oh, i bet you think that's awful!" I said "What?"
She replied "Awful that i couldn't find a calculator!"
No, sweetheart, that's not what's awful...you work in a bank and can't add up 3 figures...but i said it to myself and just walked away, slowly shaking my head...

Just for info, that was Fred The Shred Goodwins's Royal Bank of Scotland...oddly enough, he managed to count and keep his £17m pension pot...
just saying...

Anyway, back on topic...I am going to order some of those Linian clips. The wee lassie in the video has a lovely Scottish accent!

why would you use p clips with rawlplugs when the 18th says not to?

 

[davesparks]

Which regulation says you can't?

never seen a reg saying you can’t use metal p clips or rawlplugs.
it was decided ages ago that a plastic rail plug and suitable screw was a perfectly acceptable method of fixing

 

[bigspark17]

Black metal strap. Use this on ho7 & swa installs. Also take care of cleats not meeting fire rating fixtures.

A while back, a member provided a link from the grown ups at the IET about using standard plastic raw plugs. If I recall they changed their mind (again), and gave guidance that consideration should be against using standard plastic raw plugs in escape routes.

https://electrical.------.org/wirin...tumn-2015/fire-performance-of-cable-supports/

I note this guidance predates the 18th.

 

[SparkySy]

I use metal strap band with wall dogs and normal plugs and screws. sometimes I will wrap the band round the cleat so that it doesn't look out of place, other installs I have used it exclusively and still looks good I think!
