Re-wiring a old consumer unit (Read 8400 times)

Posts: 2 Total Thanks: 0 For This Post: 0 Gender:	Re-wiring a old consumer unit Aug 2^nd, 2004, 9:05am I have two old style bakelite fuseboards and want to replace both with a single split load consumer unit. However the cables are not long enough to reach where I want to put the new consumer unit. Q: Can I use wiring blocks to extend the cables to the new consumer unit?

Apologies if I'm confusing the issue! Also, why not replace the cables which are too short with longer ones? Andrew

Anything wierd can happen and one day if it can it WILL. Best be safe than sorry. RR

And surely terminal block is a bit innapropriate for extending tails, need henly blocks like Handymac said, thats if you have to extend and can't replace.

For tails maybe but a bit OTT for 1.00 mm lighting cable! Move the CU to the cables and extend the tails is usually far easier. RR
