	Nichrome wire is live with electric potential. It is useful to insulate it to use it reliably without shorting out on itself or on other metal parts. To this end, nichrome wire is coated with teflon.		Nichrome wire is live with electric potential. It is useful to insulate it to use it reliably without shorting out on itself or on other metal parts. To this end, nichrome wire is coated with teflon.

			==Design Rationale==
			*Select for power.
			*Minimize length to simplify the amount of wiring
			*Check that it doesn't get too hot for a given length with [[Nichrome Wire Calculator]]
			*Make wire thin to get lower length for a given power
			*Don't make it too thin so it doesn't get too hot.
