3 Phase Dollie Power Made Easy


Farmer client some time ago had their utility grid meter base and distribution panels upgraded to 20 kw (200/amps) 120/240 single phase when they decided to go to a auction and purchase a 3-phase corn elevator. The new distribution panel looks like the below photo it now has over head unistrut clamped riser conduits racked and underground pvc conduits racked to one distribution meter reading point on the property.



After consulting with with him on his options to get the machine running on the new single phase utility power were to (1) swap out out the motor from 3/phase to single phase  (2) Dollie Power Transfer (3) Contact utility provider and inspections for new 3/phase service upgrade. The cost of each for materials were discussed along with labor. Long story short choice #2 made the only feesiable conclusion to the remedy to get the 3-phase corn elevator machine operating on the new single phase service.
(2) Dollie Power Transfer 

A dolly setup made this a simple fix. As each barn building had subpanels updated also during the meter upgrade so the required single phase utility grid breakers were available where needed. 



The simple fix here was to mount a single phase to 3 phase converter onto the doily with plywood attached to it for a mounting surface. Finding  just the required electrictronic device required and matched to the horsepower rating of the 3-phase corn elevator motor. A 3kw 2/pole  240/volt breaker was installed at the required barn locations to feed a twist lock 3 kw female outlet in the required weatherproof box placed next to each subpanel. The same type of weatherproof outlet was installed onto the plywood mounting surface of the (2) Dollie Power Transfer board.  Giving now a source of 3 kw 240/volt  single phase source of power required to feed the  3 kw female outlet using male to male twist lock & SO cord rated for 3kw and distance to be able to roll the (2) Dollie Power Transfer beside the 3-phase corn elevator. 


Necessary connections were made to the Dollie Power Transfer board and devices and now the farmer is happy with his 3-phase corn elevator running on his single phase service.
