U-Ground Multi-Outlet Adapter

The US Wire and Cable 35003U converts a single extension cord into a three-outlet power distribution point. It is designed for job-site crews and workshop users who need to run multiple tools from one heavy-duty cord.

Triple-Outlet Conversion

The moulded U-ground housing turns one cord end into three grounded receptacles, letting you plug in several devices at once. Heavy-duty round yellow 600V cord maintains durability in rough environments where standard strips would fail.

600-Volt Cord Rating

The 600V cord insulation sets the voltage ceiling for every tool plugged into the adapter. It does not increase the amperage capacity of the upstream cord or circuit, so total draw must stay within the source cord and breaker limits.

Questions about this item

Will the 12/3 cord on the 35003U adapter need replacement after heavy use?

The 12-gauge, three-conductor cord is built for heavy-duty service; inspect the jacket and plugs periodically and replace the unit if cracking, exposed conductors or loose blades appear.

What limit appears first when the 35003U runs at full load for hours?

The 600-volt rating and 12-gauge conductors set the thermal ceiling; sustained maximum current will warm the cord before the voltage rating becomes a factor.

How much heat or noise does the 35003U produce when powering tools all day?

The passive adapter generates no noise; expect modest warmth along the yellow 600V cord proportional to the combined load of the connected devices.
