First job thoughts

[martysparky]

Just passed an EAL Part P and got a total rewire lined up.
I get the opportunity with my current job to look in many meter housings and see many CCU's.

I've seen some really old systems and have wondered what the heck is going on in some of the set ups from the main cut out. I.e. Three tails coming from the live at the meter going to 2 old rewirable fuse ccu's and switch with the neutral conductors returning to the main cut out.

What would I do in this situation?

would it be advisable to contact the supplier to upgrade their end because |I understand the main cut out block is their responsibility but the a lecky has authority to upgrade tails from the meter. seems a bit paradoxical.

Any help in this matter will be much appreciated.

thanks in advance

Hi and welcome.

From your description I would say you have a separate board (CU) for storage heaters maybe? They have been converted to sockets now if central heating is installed.

If not storage heaters, the house may have had too many circuits for a single board. Fuses boards tended not to have as many ways. It was more common (and cheaper it I'm correct) to install a couple 6way wylex
than (probably a commercial) 12way board.

Unfortunately I can't really help with out more information, which I know is sometimes very hard to describe on here in words.

You are correct about contacting the DNO if the service head needs upgrading / changing etc. You CAN NOT legally touch the service head, meters and cut out fuse.
Depending on where you are you might have problems even getting through to someone at the DNO who even know what your talking about.
EDP are terrible last time I contacted them (on a number a mate from EDF gave me, which normally works well) they kept telling me to contact EON.

Its my understanding that most lecky's just pull the main cut out without permissions. I guess if you cant get any sense from DNO thats why it happens.
