Marina calculation

[Bob Byrd]

Mike, I have a marina(Bay Hill) that they want to prewire roughly 40 lifts that will draw about 8-10 amps each. I know there are calculations for shore power, but I cannot find anything for the electrical lifts. 1HP each

How many lifts would actually be ran at any one time?

Unless interlocked to disallow concurrent operation I don't believe that will make any difference.

I believe the lifts will have to be calculated per A220/A430
