Electric Build - Stilldragon DIY Kit

[Jif]

I just finished wiring up a spa panel and four prong outlet off my main breaker box, and I have a few questions about wiring up my controller.

1) All of the diagrams online show the wiring diagram for the Still Dragon DIY Controller Kit with a 3 wire set up. Given that I'm working with four, how does this change things? I was also just planning on cannibalizing a dryer cord, as they're clearly 30a rated and let me skip wiring up a plug. Is there any issue with this?

2) I've looked far and wide for a 240v 30a switch (running a 5500w element) and can't seem to come up with one. Does such a beast exist? I'd really like the ability to have a quick full shut off switch, rather than just having to crank down the knob.

EDIT: Would a switch like this:

Work?

Thanks in advance, all.

just wire nut and electrical tape the neutral wire since your not using 120 volts.

Agree on just wirenutting the neutral capped off since you are not using any 120v accessories. If you eventually wire in a pump outlet or something like that, you'll need it. Yes, that 30a double pole switch will work for what you want to do.

Here's a cheaper option on the switch. http://www.homedepot.com/p/Leviton-...ble-Pole-Switch-White-R62-03032-2WS/100356941

I use the lighted version of that switch from HD linked above as a cheapo E Stop on my still dragon controller. Works great, simple to wire in up. Very happy with it.
