Finding an auxiliary block that has 3 N/O contacts will take some sourcing ...................normally they are 2 N/0 and 2 N/C, which is probably why 2 were recommended. Plus you need the auxiliary rated 24 amps ( can't get my head round that value) and most auxiliary are for control so that would be something else not exactly of the shelf

Correct I can't get hold of one

4 N/O contacts is not a problem but I take on board that not many aux blocks will carry 16+ amps.

I still maintain get a proper timeswitch. I have a nice 80A unit in my meter box, although I don't have storage heaters any more so it sits there looking pretty.

Additionally, once you start fitting contactors, then the client has an additional "moving part" in their system. A few years down the line as the contacts wear/burn out they will have more expense.

G isn't the No 13/14 on an Aux normally what we use to call in them there olden days a "pulse" contact. I remember the dim and distance past when doing these being told that you never connect a load onto it.

I have used many forms of aux in industry over the years, some 2/2, some 4 n/o and some 4 n/c. I realise everybody's experience will be different. One thing I did learn after many night-time call outs was this...Always use the next contact size up from that which the manufacturers say will work....
