EICR coding question

[Welsh_sparky_21]

Came across this on an EICR and was wondering how everyone else would code it. Basically there’s a sangamo time clock that controls a contactor which switches a 3 phase DB for storage heaters, strange set up in a flat. So you’ve basically got 6mm cables in this sangamo time clock that are protected by the supply authority fuse, would you code that a c2? Main fuse is 100a. Would be better if this was being supplied from an mcb I would say

An inline fuse would normally be fitted in cases like this. Similar to what you might find in the old Heatmiser off peak water heater system.

From your description it sounds like you are trying to code the DNO / electricity suppliers economy 7 time switch

Been removed now, but had the same set up in a local church. All DNO equipment.
