I built the supply cords for my heating elements. This is 10/3 wire covered with a protective/decorative sheath and 3/4" heat-shrink wrap on the ends to keep the ends from migrating... The NEMA L6-30 plugs will connect into receptacles in the control panel while the other end will be connected to the 4500W ultra low watt density heating elements.
A few evenings ago, I started on building the boxes to house the elements. The Keggles will all be bonded back to the house ground.
Friday at lunch I went to the electrical supply house and picked up 30 feet of 8/4 wire to make my 50 amp main power cable. Wow... are they ever proud of copper these days!!! Holy smokes!
Today I got my element boxes finished to the point of putting elements in them... unfortunately, I purchased 5500W elements and then decided to build a "Back-to-Back" electric brewery. I need to sell these elements now. I re-ordered some 4500W elements and it is just hurry up and wait now 'till my new elements come in.
I also built a GIGANTIC 30 foot extension cord for my rig. I am waiting for the special connector for the other end to come in... This connector is 3" diameter. I guess when you get up to 50 Amps, you want PLENTY of insulation from that current. The cord is 8/4 cable and is bigger than my thumb! I just REALLY wanted to be able to brew outside in the driveway on nice days.
