Always check with a certified electrician for code in your part of the world. We advise that you have a certified tradesman do your installation.
In Canada, an Arctic Spa requires a 50 amp GFCI and 6 gauge 3 wire plus ground. It’s the same in the United States although the wire is commonly referred to as 6 gauge 4 wire.
Make sure you leave yourself enough wire to get from the outside of the cabinet to the electrical pack inside. This distance will vary depending on which side you prefer to bring the cable through. Play it safe and give yourself an extra 10-15 feet.
