RCBO for a 6 year old Sentry CU ?

[Timbo_UK]

Hi all, New here :x (Time served sparky now mainly working on control systems for print and packaging machinery)

Just a quicky to start with, anyone know of an RCBO (10A) that will fit a 6 year old MY Sentry split load consumer unit. I think they changed thedesign a while ago and the current ones wont fit? What can I look at on my CU to check if I have an old of new version?

Thanks in advance.

PS: Reason is I am redoing my bathroom, so I need the lighting cct RCD protected so as to avoid the equipotential bonding mess. (BCO informed as other building work going on in house while I do bathroom)

Hello Timbo welcome to the forum. A six year old Mk will have same breakers as the current ones. Mk do change where they buy them from but they should fit.

Thanks for the reply, I am sure I "heard on the grapevine" they had changed their design some time ago and parts were not interchangeable?

Is main bonding in place?

Hello and Welcome Is main bonding in place?

Yes, although I must admit I need to double check the size of the bond to the water. 1890's property, water feed into cellar at front of house, plastic to kitchen at rear, then onto stop cock, then to copper (was lead).

Ill pull out my regs later and check whats needed. I have 25mm2 tails to CU.

Thanks for that, but to be honest I also rang MK's technical line to be sure.

You were correct. Applaud Smiley

Apparently if the CU has a smoked see-through plastic cover (as opposed to a solid white) then you are ok. The older style were the forked bus-bars that went under the screws, and the newer type go into a cable tunnel entry.

Hope he is right, as I have rung my wholsalers to get me one in! Sods law though he had just sold out of 10A ones!

Lifes never easy.



Be careful with wylex stuff especially metalclad as some of the breakers are not interchangeble.
