church nightmare

[Matty o]

Just did a small church what i nightmare and have a few questions on coding

The heating is by rusty tube heater groped in to 5 per radial circuit and their are 4 circuits and each circuit is feed buy its own 15amp cartridge fuse in the main CU

Now the good bit
To switch the heaters on and off they have mounted a second hand 4 way plastic enclosure below the CU and fitted 2x32amp mcbs and 2x20amp mcbs to act as switches

I am at a bit of a loss on how to code this as technically what's wrong?

Each heater has no separate means of isolation but the flex just goes into a imperial conduit box and connects using old ceramic blocks
are the ceramic blocks still ok?

Well, there never going to melt or ignite into a fire!! lol!!

Surely as long as everything passes the relevant tests then what's the problem? Churches nearly always have a series of rusty old infra red bar heaters, and the old heaters always had ceramic connections. So if everything is safe, no code.

If there is no form of local isolation for each heater i.e a durably placed or marked form of isolator, you could code it as a C3 at a 'stretch', but from sitting behind my computer, there doesn't appear to be any real problem...:joker:

An MCB to BS 60898 is suitable for use as a functional switch (table 53.4 refers).
