JBD,
Thanks! I learned something today!
Just a couple more quick questions if I could:
I'm assuming that you got the typical numbers from experience; however, are you aware of a handy reference that has this info in it (i.e. typical inrush and
outrush multipliers)?
Also, using the info given and your comments the inrush would be:
1) 30A inductive/resistive
1x or 30A
2) 1HP (760 W)/120 = 6.3A motor
6x or 6*6.3= 37.8
3) 5A tungsten
14x or 14*5= 70
4) 20A ballast
4x or 4*20 = 80
Total inrush current (30+37.8+70+80) 217.8, correct?
The continous current would then be right off the plate or (30+6.3+5+20) 61.3, correct?
So when you say at the end of your comments above that the switch rating must be about 3x, given the calculations above this makes sense in that 217.8/61.3 = 3.5
If I've got my stuff straight to this point, my only remaining question would be why do you mention 90A at the end of your response?
Thanks again!
