30 amp sauna heater that I need to wire. I plan on using my dryer outlet which is 4 prong but my sauna heater is 3 prong if I'm not mistaken as it has "L1, L2, ground."
My question is could I purchase an 8/3 and just cap off the neutral on both sides?
I plan to run the cord about 25 feet from the heater to the dryer outlet.
I plan on buying a NEMA 14-30P but capping off both ends of the wire. Is this okay or is better to just electrical tape it?

Connect the neutral to the plug if using 8/3 cord. Put a wirenut (and tape - this is one place where taping a wirenut is reasonable) on the unused wire at the heater end of the cord.
IMHO it's also perfectly reasonable to use an 8/2 cord and leave the neutral prong disconnected, since the appliance does not need neutral, but if you are using 8/3, connect it to the plug.
