One for the Electricians...

phill79

Hi
Just after some views from electricians as to what, if any, laws the image below has broken. The image shows a projection wall beam mount (a pole from the wall with a projector on it) and the electricians have come in afterwards and mounted that socket where it is along with the trunking going over the actual wall mount fixings (with the backs of the trunking cut out).
If anyone can let me know I would be most appreciative.
Thanks

Were the electricians Part P qualified? If not I would get the work certified by someone at the relevant council department.

As a non electrician, my immediate concern is earthing.

Unfortunately Part P is only for domestic installs. More worryingly, the school where it is at is an Academy so doesn't even fall within the council remit. This is why I am doing a bit of research first before I bring it up. But yes, I wouldn't be happy touching the beam that is for sure!

Having nearly £500 to pay out when the gas pipes went live despite being earthed I can see your concern. Are there any Part P electricians you could ask to have a proper look?

The electrician I use also does all the work at one local academy & he is Part P qualified.

Do we know what is is wiring inside the plastic conduit?

'IF' it is full standard twin and earth inside its mechanical protective external grey/white sheath then it is no different to clipping cables to whatever up the wall
(or draping them over pipes, metal fitting and the rest under floorboards as happens in every house).
The plastic conduit-ing thingy being just there for aesthetic reasons.
Edit - Indeed no different to the status of the projector plug/cable itself which will be draped from the plug across the support assembly to the projector itself touching the metal with its outside sheath as it goes.

If however it is single insulated individual conduit wires for LN and E inside then I agree its different.
The metal construction assy should then be earthed as any normal metal conduit would be.

Is there any reason to think that the electricians who carried out the work were unqualified and it was done incorrectly?

If not then nothing to worry about!

No reason, just a rubbish install. What happens when the pole needs to come down, the only way to do it now is to unscrew the back box.
I really just wanted to make sure that what they have done hasn't breached any regulations.

Can't see why the back box would need to be unscrewed if like you say they have cut away the back of the trunking that passes over the fixing for the pole the fixing could easily be removed by sliding out once the bolts to the bracket have been removed!

And in the scheme of things, removing the back box will take seconds.

Thinking as a non qualified diy'er , wonder how I would have done it .

............ exactly as the installer had done. Looks neat.

I agree it looks very neat and tidy, I have seen far worse installations that were supposed to have been done by so called professionals that's for sure!

Indeed it would take seconds, but working with electric in anywhere the public has access is a whole different world to your own home.
These people are "professionals", not "non qualified diy'er", so you would expect them to do a better job, unless I am the odd one here.
