1.5mm coming from a 20a isolator

[rugbylad]

What is people’s opinion on 2.5mm swa entering a rotary isolator and a 1.5mm swa leaving on a 20a mcb? Having a bit of a discussion with a colleague.

what's the load current/wattage.and is it a fixed load?

Single phase or 3 phase?

There’s a 1kw heater and 2 led lights not sure what wattage they are but they’re not huge just in a little store.

Single

Should be fine, unless it’s in a wall with insulation.

Well I think it is acceptable, it can take a round 24 amps with it being on tray and clipped in places, the total load probably won’t be m0re than 10amps and I’d say at a rough estimate theres about 25m of swa, so no issue on length of run.
