voltage drop on subpanel feeder

Hi Guys, I'm running 200 feet of aluminum 2224 to my new garage for a 100 amp subpanel but the guys at Lowes are telling me I'll have too much voltage drop and end up with 30 amps out there. I am gonna run an electric boiler that sucks 47 amps lights and door opener and tv and such thanks for any help

Gotta love those guys! You are worried about voltage drop and they give you Amargeddon about amperage. I figure you will have a 2.9% voltage drop considering what you have told us, meaning your end voltage will be about 233 volts, well within parameters.
