Can the XTB-II/R be connected to a 240V dryer outlet?
Yes it can, especially if the dryer outlet is relatively close to the main distribution panel. However, the conductors in a standard dryer cable are too heavy to connect to the internal terminal strip. Three or four conductor 16 or 18 gauge 300V power cable can be wired to a separate dryer plug that can be purchased at a home building center or an electrical supply store. Be sure to purchase a plug whose prong alignment matches your receptacle. If the dryer outlet is a long run from the main distribution panel, it would be better to try to locate the XTB-II/R closer to the panel.
