I arranged a new LG dishwasher delivery/install for a client tomorrow, and just learned the dealer doesn't do hard wire hook-up's. I need to run the wire to a handy box in the adjacent sink cabinet so they can test it when they're there, etc. and am wondering about box placement. The guy in the store ball-parked the cord length at only about 18-24" - does that sound right for a standard cord? Sounds short. So outlet goes on side wall and not too far back in these cases? Thanks.
