UK New Sub Board for aircon

[MattBaigent]

It's a very specific question so you must have a reason for asking that question. So why do you think a fuse switch would be required?

It appears you aren't just learning but are attempting to complete work by getting the forum to do your designs for you.

because before my DB at home I have a switch and I’m wondering if it is common practise or just someone has specified it.

I will be installing the cable to the aircon units but I will not be terminating it and this IS me just wanting to learn and work out for myself how it would be done, and funnily enough I was unsure so I came on to this forum for advice from lovely kind people such as yourself

A switch, what type of switch and where is it installed? Is it a DNO provided isolator?

There's a big difference between a switch, a switchfuse and a fused switch.

yes it is a DNO provides switch. I have my 100A fuse, the meter and then the switch. So I was wondering if this was common practise to have some form of switch to isolate the board or if this was just requested by previous owner.

An isolator between the incoming supply and the consumers installation is an ideal scenario.
But that's very different to installing an isolator before every DB in an installation.
