stick 'em in, switch on, measure the VD. if it's under 220V at point of utilisation, then start worrying.
Ye gods, common sense?
No, I must be on the wrong site.

Is this a Greenhouse or Sauna or for growing "Something else"?
Make up an extension lead of 2.5 t&E, borrow a 3kw fan heater, and do some tests.
I'll guess the greenhouse will get warm and light and the cable won't melt and the volt drop Police won't turn up.
the fault current would be proportional to the voltage, so if the volts were down by 10%, then so would the fault current be 10% less. 900A as opposed to 1000A. don't think OCPD would be too bothered by that.
