...but true.

Recommending replacement is one thing, but doing so through dishonesty or incompetence is another matter entirely.

Your image shows a 15 module board. 12 module busbar would be far too short and I can't imagine why an electrician might suggest a 15 module busbar would be too long when that's what is currently fitted in the board.

Crabtree Part No. 9150 for 15 module mainswitch busbar.

If you want to fit a new board, then by all means do so, but it's certainly not the only option. Mathematics is an essential component of training for every electrician, yet you seem to have an electrician who can't even count into double digits!

I see it as 12 module.

I see it as 12 module.

I'd scrolled up to the attached image and counted 15.

Turns out the image was one you'd posted and not that originally posted by the OP


Apologies to the OP and their electrician!

In old Crabtree catalogues Starbreaker busbars were described in terms of total number of modules wide, although latest catalogue seems to include only modules after mainswitch. Either way it seems Crabtree no longer offer a mainswitch busbar to suit the OP's board.

and also untrue.

Fixed this for myself

I only count after the switch mine is actually 13 as the RCD is 3 modules.

All they needed to do was fit RCBOs for the left side job done. The RCD is AC but that to me is an advisory.

I would generally count usable modules, but Crabtree used to disagree. Didn't realise they'd changed this position until today - in fact, looking more closely they now describe it as both 'main switch/rcd + 13 module' and '15 module' on the same page.

Westward 10 mentioned 12 way busbar and thats what my electrican thought as well but it didn't fit. 15 way busbar was too big he said. He would not have changed just 4 RCBOS on the left, he said he was going to change to 6 x RCBOs by taking out the two RCDs on the right and the RCCBs so leaving just the main switch as is and 6 x RCBOs as there is a chance of tripping he said if the RCDs were left however the plan didn't work which is a shame as I was hoping to avoid disturbing the walls so next week it will be the Fusebox F2020MX board with the mounting frame installation.

totally agree with westward in post 17, that is exactly what I suggest and it is not a difficult job at all. By the way my DB is similar and I see no need to alter it but if you have to the RCBO way left side is the most sensible
