Air conditioning unit

[Elliott96]

Im putting a new circuit in tomorrow for an air conditioning unit (im just doing the supply side). Am I right in thinking a standard 30ma rcd and b type breakers can’t be used with air conditioning units?

10mm too small vd wise. I think I'd be going swa all the way, too.

May I suggest to the OP that they do the calcs for what they intend to install and come back to us for a double check?

I know I've taken the mic a little bit and that has been deleted.
slap on wrist accepted.

but only the OP knows the installation methods and can judge what is best practice.

perhaps, if the OP posted the installation method, overload device and expected current it would be good to see some of the trainees use it as a real world practice.?

Any chance of getting the ac unit changed to 3 phase?

Noticed that this model of a/c is silent on running current max.
If it helps with your calcs, a similar a/c unit fused at 25A and 10kw output states a max running current of 20.6 amps. From experience the running current is much less as in our climate the fan(s) very rarely run flat out. Startup current is less of an issue , will be around 12 amps.
I fit a/c and if i was running a supply 100M i would be getting the books out on this one... lol
Good luck,
