1.5mm² lighting cables - 3 lights- do they have to be in-line?

b) I wasn't asking about the regs, was I?

What do regs allow?

 

[ban-all-sheds]

additions or new circuits come under regs

Is the OP installing a new circuit?

 

[JohnW2]

Doesnt come under regs.......

What on earth do you mean by that?

Any electrical work most certainly 'comes under' Part P of the Building Regs (i.e. 'the law') and breaking the law, rather than not complying with BS7671, is what might conceivably get you into the court you appear to fear.

... and i wouldnt advise them to start with.......

... which leads my curiosity to again wonder why you are contributing to a 'DIY Electrics' forum.

Kind Regards, John
