Above 40 amps you should be using the 6awg. Especially considering that it's a 30 ft. run.

How much wattage do you plan to pull? That will determine how big your breaker and wiring needs to be.

I used a 50A breaker and 6 ga wire so that I could run 2 pots at once.

FUSE MINIMUM WIRE
15 #14
20 #12
30 #10
40 #8
50 #6

There are exceptions but for our purposes, this should get you by.

Theoretically, I'm only planning on running one element at a time, but I'm building such that I could run 2 in case. I found online that there are actually grades of insulation that impact the amperage allowed. I can run 55a on 8awg, but it has to have the top level insulation 90 degree C. I will likely go 6awg. Fun will be fishing it all through the conduit.

This is only used in derating. The NEC lists the minimum wire size based on fuse/breaker size.

Gotcha, glad I budgeted for 6# then.

So i checked my 240v service on my dryer. Confirmed, my voltage is 270v. Any ideas anyone? Why so high?

I have no idea what to make of that, but I'm curious do your 120v outlets read 135v?

Everything is as any other home. Nothing is marked any different. Thinking this is Houston's idea of 120/240 and i'll just have to roll with it. I am using 10# wire on the elements anyway, so 30a breakers inside, should be all okay.

Is your meter accurate? If it's digital, I have a few that are all over the place. I have a good old analog meter that I use when it's critical. Test with another meter if you can.
