Abstract

A cord-connected mobile power supply which consists of a transformer for converting 480-volt power to 240-volt power and 120-volt power, a distribution panel means for providing over current protection to branch circuits, which have ground fault interrupter receptacles for connection of utilization equipment, which can be modified to accommodate different equipment requirements or GFI protection of branch circuits, and which has a transporting means consists of an adapted narrow L-shaped dolly frame with an extended platform having two wheels and handle.

Claims

1. A mobile power supply comprising

A. transformer means for converting 480-volt power to 240-volt power and 120-volt power,

B. distribution means providing over-current protection and electrical access to 240-volt and/or 120-volt power, and

C. outlet means for providing power for utilization by equipment;

and

D. means for transporting the voltage converter.

2. The mobile power supply of claim 1 wherein the means for transporting the voltage converter comprise an L-shaped frame having two wheels and a spine means for supporting the voltage converter.

3. The mobile power supply of claim 1 wherein the means for transporting the voltage converter comprise a frame made up from tubular members, having a support platform extending perpendicularly from the frame, having two wheels affixed to the frame where the support platform extends from the frame, and a vertical spine means for supporting the voltage converter.

4. The mobile power supply of claim 1 wherein the transformer is a 5 kw single-phase transformer.

5. The mobile power supply of claim 1 further incorporating a distribution panel and circuit breakers.

6. The mobile power supply of claim 1 wherein the outlets are ground fault interrupter receptacles or multi-pole ground fault interrupter breakers.

7. The mobile power supply of claim 1 wherein the means for transporting is less than 20 inches wide.

8. The mobile power supply of claim 1 wherein the receptacles are changeable to accommodate varying utilization equipment configurations.

9. The mobile power supply of claim 1 wherein the circuit breakers are changeable to provide multi-pole ground fault interrupter protection.
