no earth terminal. what would you do?

[telectrix]

as title. using existing back boxes ( lighting) as original VIR cable in capping and managed to re-use route to save chasing. boxes are tight and nailed in. removal would cause a lot of damage to decor. no earth terminal in box, so my solution was to drill the side of the box and fit screw. obviously a 2mm HSS bit is no good to drill into the brick, that's why it's in the side. would have been neater if I'd gotmy box of ring crimps on site, but hey ho. at least the box is earthed.

Get some multi-drill bits to drill the box and masonry, might bugger the tap after a while but at least you have a decent connection.

 

[elsparko]

get 2x washers, put the cpcs between washers looped round the screw and bang it in

 

[telectrix]

sod it.i get a R1+R2 = 0.67 ohms. approx 30m of 1.0mm T/E. ticks the box afaik.

You know Tel it ain't a good job.

 

[buzzlightyear]

I have one of these in my van for jobs like that.

It looks rough, it is rough, we can all see better ways of doing it, but it is technically compliant.
Sometimes you just have to get creative to do the best you can with a job, but then you have to accept that anyone seeing the job may well put you down as a bodger and a cowboy.

It’s no different to the earth terminal that comes in a new back box anyway. All they are is a screw at the back and not the side. I would probably lug the cable and fit a self taper myself but thats me being over ----.

Don’t worry Tel we know you ain’t no cowboy but sometimes needs must.

 

[telectrix]

would have preferred a pan head screw and ring crimps, but none in van. no wholesaler close, customer gone walkies so could not leave site. so far only 4 switches done, so might alter when back on site.

The thing that causes hassle Tel is the original bodge installer fixing the box with a bleddy great nail. If it was a screw I'd replace it with a new slightly bigger one and put the cpcs under it [making sure any paint or corrosion is removed in that area],either ring crimps on the cpc/s or a washer. Fair play to you for posting up the picture, I'm sure there's at least 3 of us on here who aren't perfect.

would be nice to do that, but box nailed in, 1950's plaster tight round box. getting box out would lead to the room needing redecorating. sometimes you need to balance the costs. already re-used the original capped channels to save chasing.

I like the look of those Deta chaps...but in the field, it's a different world when you have to make do with what you've got.
I agree that drilling and tapping is tricky in situ due to the masonry drill messing up the hole in the back box. At the end of the day, when all's said and done, and in the final analysis, going forward...(UGHH!)
if it is tight, fast, does the job, well what more can you expect...it's a CPC and it is solid.
Personally, I have found that many of the modern screws are excellent at self-tapping and providing a really good hold, so when fastening to metal I drill a small pilot hole and then, by hand, screw a woodscrew of the Turbo Ultra Gold type in, with a suitably sized washer on it. By hand, you can just tell when it's nice and solid, by virtue of your own built-in torque sensor in your wrist. Also, if the stonework is very close behind, the sharp points on such screws will easily penetrate to allow the full screw depth to be accommodated. It's all about a solid connection. Looks like a good job to me, Tel!

True, but in my retirement I have learnt so many songs that I can now confidently say that if you give me a name, boy or girl, I can find a song with that name in it...and because I am an old git, I know I have done this before!
Anyway, leave a safe job...Tel, you did.
