If you're in the process of installing a dishwasher or replacing an old one, you may be wondering what size wire you need. The answer depends on the wattage of your dishwasher and the voltage of your home's electrical system.
For most standard dishwashers, you'll need a 8-gauge wire. This is a heavy-duty wire that can handle up to 50 amps of current. If your dishwasher is particularly powerful or if your home has a higher voltage system, you may need to use a 6-gauge wire. This can carry up to 65 amps of current.
When in doubt, it's always best to err on the side of caution and use a heavier gauge wire. It's much better to have too much capacity than not enough!
