Heating system in a local church which is basically tubular heaters under a few pews.
A local company has already quoted thousands to rip all this out and start again. The committee are reluctant to spend massive amounts as the building only gets used for 2 hours once a fortnight.
It’s old, but it all works.

Main switch on left is always on to power everything here.
The silver box next is a contactor.... will get to that in a minute..
Next is the mainswitch for the fuseboard... they turn this on during the week before a service.... but only sends power to the top of the contactor.
Next is the fuseboard.... 6 fuses across 3 phases going out on the old twin and earths that disappear into the wall below it then go to heaters.
The rightmost MEM switch doesn’t get used. Neither does the circular mechanical time clock below.... which is marked as suppliers clock.
The electronic programmer beside it appears to have replaced another mechanical clock which energises the contactor coil.... the switch below that overrides the programmer.... which is now surplus to requirements as the electronic programmer has its own override button.
So, just to make things a little safer without tearing it all out, could I take the guts out the fusebox and install a DIN rail with rcbo’s?
Leave the box and lid as it is, but fix a Perspex shield with a hole for the rcbo’s to stick through so they can be reset, but all the connections are safely behind the barrier.

Whew... long post.
There’s a fairly modern 4 gang plastic CU elsewhere serving lighting and power, so I’m quoting to change this to rcbo as well.
ps, the other box a foot below the switch is a room thermostat, and if it’s also surplus, it’s coming out for LN.
