Type of wire for 5500w 240v element
 
By my calculations, a 5500W element at 240V will draw 23 amps or so at full load. That says I need some 10AWG wire. What kind of wire are you guys using? I'm thinking about just buying a nice 10 gauge extension cord and cutting it up. Is there some nicer rubber coated wire I should be using?

23 Amps, 10 AWG. 8 is over kill, unless the run is long (80ft+.)

I just did my first PV system.

I think I'll keep my scrap #10 XLP PV WIRE -40c 90C wet or dry sunlight resistant scap wire. It's the best there is.

You should be able to get 10awg so/sow cord from lowes or home depot.

You have all your numbers right. Well done.
The cable type depends on what you are doing. If this is an equipment cord (attaching to your element) you will need a rubber cord, like SJ or S. It may be called something like 10/3 SJOOW for example. If it is the cable feeding your outlet you can't use rubber. Here you'll need UF for example. The guys at HD or Lowes will know which type you need, most of the time anyway.

For each kettle I use 10 feet of Carol brand 10/3 wire (10 gauge, 3 wires), 300V, oil/water resistant, rubber coating, rated for outdoor use:

Available at Home Depot.

I then purdy it up a bit with some heat shrink tubing, and expandable sleeving:

That is purdy, but IME nothing stays that purdy. I try to keep the equipment shiny (i.e., polished kegs), but use and age take their toll, and in the end you have to choose between utility and brew-fashion.

To quote our American poet laureate, Robert Frost:
Nature's first green is gold,
Her hardest hue to hold.
Her early leaf's a flower;
But only so an hour.
Then leaf subsides to leaf.
So Eden sank to grief,
So dawn goes down to day.
Nothing gold can stay.

I dunno, after almost 2 years of using it and dozens of brews, the wires, covers, boxes all look the same! The inside of the brew kettle's a bit tarnished (as expected) but mostly because I don't scrub it completely until it looks like new after each brew. I only use water and elbow grease. Then about once a year I recirculate hot PWB or oxyclean through it to give it a really good shine.

My cords stay filthy, even after hosing. That cord sheath looks like it would trap a lot of grime, but I'd give it try. mcmaster?

eBay. If you spill something on them it would most certainly be hard to clean. I've never spilt anything on them

When I clean my boil kettle I simply tilt it sideways into the sink and use the pre-rinse washing arm to scrub it clean. I don't clean the outside.
