Stop in for a cup of coffee
A pool pump shed - my sister-in-law bought a 35kW heat pump for the new pool. Sub-main the size of the house mains....lol.
I supplied the cable and duct, so it was up to me to certify it, and lay in the trench. Another local guy is wiring the rest. I live just over an hour north, and my other work would suffer if I got caught out down there and not able to get away.
