Leesburg, Ohio | All of our portable sweep augers are run on motors wired for 110v. Plenty adequate for a 1.5 hp motor, and that is enough motor to run a sweep in a 36 foot bin.
Larger bins have power sweeps, and I suppose if they were not, they might require a 2 hp motor, and 220v would be more suited there.
All portable sweeps run on a standard 110v outlet next to each bin door with a standard light switch to turn on and off.
We use all L6-30 twist locks for bin unloads and truck loading augers, again located next to each bin door with a heavy 30 amp light switch to turn on and off, so we can control everything from inside or outside the bin.
Over time, we have replaced the 30 amp light switches with NEMA magnetic starters for each circuit at each bin. This is the correct answer, since switching a 3-5hp motor with a light switch or a breaker will arc and burn out the breaker or switch over time.
All larger bins are hard wired with magnetic starters with built-in overloads.
I buy NEMA rated mag starters on ebay for a tiny fraction of what they cost new, and I find the old Square-D mechanical/heater strip units to be much more reliable than any new, high-priced electronic ones.
If you use a portable electric auger to load trucks, you can save cost by mounting a mag starter on the auger instead of having one at each bin...just have to have three circuits at each bin, one for the sweep, one for the bin unload, and one for the portable truck auger. Only the bin unload needs a dedicated starter at each bin, unless you make one of those portable to move with a motor to different bins, like the truck auger, then only two starters needed for the entire setup. The 110v sweep can run on a 30 amp switch at each bin.
Nothing wrong with using welder plugs instead of twist-locks. There are a million styles of twist-locks, and no two will match (by design), and they can be pricey, and hard to find. Welder plugs are available about anywhere. | |
