If lightning is an issue then you need protection
We’ve had a site where where multiple Auditors have failed – catastrophically, with repeated lightning strikes the suspected cause.
My suggestion would be to install a surge protector.
If there is not much room, then a single phase protector on P1 should be adequate.
Best is to use a protector on each of the three phases.
Wattwatchers can supply both single phase and three phase surge-protectors.
Installing surge protectors will protect other equipment on the same circuit, extending the value of taking this precaution.
Lightning can be expected to become more intense and more frequent as climate change ramps up.
