I have a good one here.
Came across a new Hot Tub installation where the tub requires 240volt, no neutral required, nor a terminal to place it. (In other words, fed like a standard electric hot water heater) However, as we all know, the NEC requires GFCI protection for hot tubs. But we also know that in order for a 240 volt GFCI breaker to protect said hot tub, it requires a branch circuit neutral to operate for a hot tub that does not have a neutral!
It gets better: The installation instructions from the hot tub states, in black and white, "Do not install onto a GFCI. Use only a listed 240 volt breaker."
Yeah, while it is nice to have paperwork to cover one's behind when approaching the inspector, do any of us really enjoy fighting this battle? Hell no.
It seems to me NEMA and the NEC Board members are having a pissing contest, and I'm getting sick of it.
