Default 22 gal pwm kettle

i have a 22 gallon kettle on the way that i plan to build as electric. i got this size for 15 gal batch capacity, but will be running mostly 5-10 gallon batches. and plan on running a pwm with 5500 watt element. i'm going to be heating the mash and sparge water in the bk and will not be running a rims/herms-i just want to use the pwm for simple boil strength control. i know the 5500 is more than enough for 10 gal and overkill for 5, but i want to have more power than needed and to help speed up mash and sparge times.

i've been spending a lot of time trying to wrap my head around all of this electrical stuff. I have a 240 v outlet for my dryer- will i be able to run some sort of extension cord from the outlet to the box for this to work?

Yes, but how long are you running it? That will be a fairly expensive cord.

15 ft if i want to brew outside. in my current townhouse i'm renting the dryer is right off the kitchen, so conceivably i could brew in the kitchen but i also would like to be able to run the cord out the door outside.

You're probably looking around 5-6 bucks a foot for the cable, then the connectors on either end.

I don't remember what I payed, but mine wasn't nearly that expensive at HD or Lowes. Don't remember which now.

You'll want 10g wire. Find out what you actually have power wise on the outlet. It will be between 240-220 likely. 5500W/the voltage will tell you your actual current draw. Your cable needs rated to at least this value.

You need 10 gauge SO cable for that - It's not more then $1.00 a foot if you look around for it.

(Assuming your dryer is 30 amp 240v) If I were you I would build your control box (Housing the PWM) with a 25 foot 10/3 whip and the appropriate 30 amp connector on the other end.

Put some duct tape over the gauge - Or better yet - Replace the high pressure gauge with a plug - High pressure gauges are useless!

Where do you find it for less than $1/ft?

Might have been $2.00/ft
Buy a 10 gauge extension cord and cut the ends off.
