I just got a new to me Spa, the issue is my wiring to the SPa box does not contain a neutral. The service is very far from the spa box so I'd like to avoid running a new feed. This is the owners manual for the Spa http://platinumhottubs.com/manuals/TheLegendOwnersManual.pdf Is there a way to wire it where I do not need the neutral? This will not be inspected.
