Ship-to-shore and shipyard power
Welding, grinding and tool power aboard a hull under construction or repair, fed from the yard's 600 / 480 VAC supply and delivered as GFCI-protected 240 / 208 / 120 VAC. Units for yards are built to be craned aboard, stacked between jobs, and connected safely by people in a hurry.
Built for the yard
- Decontactor-style receptacles
- NFPA 70E decontactor-style receptacles: the plug switches the load off before it can be withdrawn, so a connection is never broken under load.
- Stackable, fork-slot skids
- Frames that stack for storage between jobs and lift by crane or fork onto a deck.
- Standards
- NEC-compliant, CSA / UL Listed designs, with designs listed to UL 1640 for shipyard units.
- Scale
- From a two-wheel cart to distribution skids in the 1600 A class, feeding several work fronts from one shore connection.
