Welcome to the site.
What device trips?
*MCB/Fuse
*RCD/RCCB unit
*RCBO

If you disconnect the boiler does the tripping stop?

Not being funny, but please try to use better written language - that way you might get a few more replies.

cheers mate its proteus geyer b6 mcb keeps tripping i ddint disconnect boiler

(Yes, please use punctuation.)

Is the boiler actually wired to this lighting circuit?

Could the new boiler work have caused any hidden cables to get drilled through or damaged?

Were floorboards lifted?

Is it a loft above the bathroom?

Is the boiler in the loft?

Can you take photographs?

im sorry bud i know i am **** spelling

 

[PrenticeBoyofDerry]

Out of interest, what fuse did you replace?

It is possible that the work undertaken by the boiler installer has caused this problem or could be coincidental!

So is the boiler or any of the newly installed controls, in the vicinity of the circuit that supply the bathroom lighting?
Has the boiler been connected to the bathroom lighting circuit?
Did this issue start immediately after the boiler was installed?

As an electrical engineer I am sure you understand what a switched mode power supply is. The extra low voltage lamps would have originally used a transformer but today we use switch mode power supplies.

A B6 MCB will trip on the thermal side with 6A but that takes some time the magnetic side needs 30A to trip so speed does matter slow trip over 6A fast trip over 30A.

So are you looking for a switched mode power supply or a simple transformer? With switched mode there is a lower limit with a transformer only an upper limit so switched mode will often not work with LED lighting.

This is a transformer 50W but this is a switched mode power supply in both cases 50W so what are you looking for?

I am also an electrical engineer and dyslectic so come one you I am sure can give us a better description of what you want?

So it is a light transform issue.
Plenty of stockists about, isolate circuit, prove dead, remove the transformer, make safe the live terminal ends before re-energising. Then take tranny with you to local wholesalers or screwfix, toolstation, wickes, homebase, B&Q etc... and get like for like tranny.
