Good point Adrian!..
Even though my place is fully fitted with RCD's..I'm now considering using low-voltage supplied by a lab grade transformer (1.5 to 12 volts 1 amp) kept indoors then via an underground conduit supply cable to a pier-mounted outdoor powerpoint...which is fine for me as I have 1.5 to 3 volt requirements..but when in doubt for mains power..call an expert about your power needs!
Cheers!
