Yes, the manufactures specs tell me to use a mininimum 100a disc. and the maximum momentary current draw is 152a, the code says I can use 50% of max momentary current draw to size my branch circuit conductors, but, I called the manufacturer and they said it would only draw the 152a for .5 of a second. So how do I size the electrical service? Do I use 50% of the max mom. current draw(75a) and add that to all three phases of my service?
