Replacing bathroom strip light with mirror with inbuilt light

vicwatson

Strip light only has Neutral and Live connections, new mirror with LED lights has an Earth connection.

Does a new cable need to be run for this install?

The strip light has a built in on/off switch and the mirror also has an on/off touch switch

Thinking aloud, I wonder if the cable is earthed to the spur and they just took a Neutral and Live off it.

Yes a new cable is required

the circuit should also be rcd protected

only a rec is permitted to do electrical work in bathrooms

Yea I’m aware of that thanks for post

Wouldn’t the existing light be RCD protected already

Depends on the age of the installation

id say it is unlikely if there’s no earth

Surely you can see the CU and tell if it's an RCD?

vicwatson

No, there's no markings on the Consumer Unit

Then it’s unlikely to have rcd protection. If a new cable is installed then it has to conform to current regulations

vicwatson

Well there are no markings on the CU for any of my circuits

vicwatson

What’s going on here?

Sparks used the wrong coloured cable

theyll need to be replaced anyway as there’s no earth. Post #2 covers it.

vicwatson

Why did they use 3 neutral cables I wonder, hmmmm

Probably used blue for all the lighting , not very clever

any test buttons?

3 neutrals could be loop in, loop out and feed to the light just like a standard ceiling rose. would need to see more of the wiring to be sure e.g. where the red cable was coming from/going to

The red cable is part of the strip light. The strip light just has neutral and live connections
