So.....maybe don't take my expert 'cough' advice. Tonight I was installing the dishwasher in suite I've been building for a client and when I went to trim down the wire hanging out of the wall I got a nasty surprise. Seems someone had flipped the breaker and the wire, which has been hanging there for a month, was live. At least all I need is a new set of cutters as mine got arc welded.
Always check those breakers.
