I’m fortunate to have a great place to work on projects, the workbench is a Workplace Systems Series 1000 with a fixed riser assembly and a 20A wire-through. The wire-through has not been used previously, but the Tripp Lite power strip is maxed out, so the additional outlets are needed.
A heavy gauge power cord was sacrificed for the project, the end removed and insulation stripped back. Since the wire is stranded, I tinned up the bare wire so that when tightened the wires would not fray.
The knockout was removed and strain-relief was added and cable installed.
An easy job, and now there are an additional three outlets to use!
