Here's some shots of a homeowners way of getting the overhead power lines for the garage outta the way! Note the metal pipe holding them in the air! Homeowner allowed me to disconnect them =) Gave a price for going underground, hope he calls! Also advised him on his choice of weatherproof outlet covers & the invention of GFI protection..
Wiring out to garages and sheds if often very poor here in England as well. Many people just don't understand the added requirements for outdoor stuff.
