Have a licensed electrician confirm the circuit against your local code before delivery. One small note for completeness: Jen-Ken lists 8,600 watts, while 240V at 36 amps works out at 8,640W.

Buy the 38 if your work is long — panels, counters, platters, sink bowls. Buy the 26 if it is square, because it costs substantially less and needs less floor.\u003c\/span\u003e\n\u003c\/div\u003e\n  \u003cdiv class=\"d-faq-item\"\u003e\n\u003cspan class=\"d-q\"\u003eWhat actually comes in the crate?\u003c\/span\u003e\u003cspan class=\"d-a\"\u003eJen-Ken does not publish a crate contents list for every model, so we do not want to guess.
