I know some hate NF questions here, but I have found great use here for NF questions, reason being, so many knowledgeable folks here. Anyways, to my question, I am replacing the power cable to my dishwasher. I had a buddy of mine make up a cable for me rated for 300V, however, when I actually checked the wires on the dishwasher it revealed a rating of 600V, was printed on the outside plastic on wires. I talked to a guy at Home Hardware and he said that hooking up my cable would be fine, I just wanted to pass it by the folks here first before I proceed. Not sure the year, but its a Kenmore Ultrawash dishwasher.
