There is 1.5mm t&e cable running to some outside lights on the wall. Doesn’t look that old but is white. There are three LED fittings totalling 40watts
They are out of reach and test ok, with a mega. However I want to replace them , preferably put them in conduit. Or run a new black round cable, but which type ?
They currently run to the fuse box into a lighting circuit. Should I fit an RCD before the cable runs outside ? My main thought is to run a 1mm rubber sheathed sold core cable along the wall and terminate wit a 3 amp RCD plug into a socket in the garage. Taking out the fuse box connection
essentially I am replacing an existing install but read conflicting pointers as to the correct materials. I am an, old, electrician so happy with doing the work
