That's current draw, not RCD.

An RCD measures current between active & neutral and trips if the difference is greater than some threshold.

I have tested an 11kVA on a hardwired outlet with an RCD with no problems.

(MGE Comet EX RT11, with 140kg of extra batteries :)

Pretty sure a 3kVA UPS would have a 15A socket and you would need to wire a circuit specially (just like for an A/C)
