I am replacing my existing 240v spa blower. The spa is only a small half moon, seats 5, adjacent to the pool with spillover. Since the existing electrical circuit, connected to a dial Intermatic timer, is 240v, the existing blower is 240v, no choice.
Since I am putting in a new 100amp sub panel, should I stay with 240v for the new blower, or will 120v be sufficient? Each come in the same HP choices, so what's the difference?
