Did he write that he's using 240V?

Industrial wiring practice here is to tag the incoming 3-phase wires
L1, L2, L3, then prefix them with increasing numbers as they pass
through switches, breakers, etc.

Single phase AC is likely to be marked Hot, Neutral and Ground (ACH,
ACN, GND, z.B.) although company drafting standards vary.
