The wrong cable?

[DVader]

Hi all

I have wired up a frame with 3x 4w led lamps, using 0.75mm 3 core flex. Each has a 2m run from a junction box.

However, when I came to strip the ends for the lamp fitting, the cable is 0.5mm. Guy in the shop gave me the wrong cable.

Is 0.5mm ok? or should I strip out and replace? The cable runs through the pipe work of the frame and will be a nause to refit.

Thanks for any advice.

It's fine - as long as it is rated for 240V if that is what it is.

 

[SUNRAY]

are these 12V or 230V

230V will be fine with 0.5mm², 12V will still be well under current rating of cable but some will start mentioning volt drop

 

[DVader]

Yes 240v.

Brilliant, thank you Gents. that saves me a lot of work and worry.

Oh no they haven’t!!

Metal pipe work, with the single insulated wires of the flex exposed where they leave the cable sheath and enter the lamp-holder? Don't forget to connect the CPC (earth) to the pipework and ensure continuity throughout the frame. Otherwise if a core comes adrift and contacts the pipework you might get a surprise when you dust it.

Hi Dave. Yes I have made sure of that. All joints are bare steel and tight, so continuity throughout. Additional earth wired to frame.

Three years ago I had a new boiler fitted. When the guy finished the installation I dusted the new pipework and ..........zapp! He was a Worcester Bosch and Which Trusted Trader! Obviously not an electrician.
