In Denver, CO, the house is a 1950s home. The compliant was there was never a washer and dryer. Today, we piped it in. We brought in a two pole 30amp breaker, put a tandem breaker in to make space for the washer 20 amp. We brought it done and in flex 45 feet. We had to go through 14 inch brick wall. We flexed it in over the mud sink. Code states that you have to have protective GFCI within 5 foot. We put our 240 volt outlet in. The washer has a “L” shape neutral on that. It is 4 prong 30 amp. We check our continuity test to make sure we bonded both boxes through the panel to the Earth. Thanks for joining us!
