Sub-Panel Roughed-In

July 13, 2020

I’ve been working on the sub-panel the last couple days.

This main-lug panel is rated for 125 amps and fed by 1/0-1/0-1/0-2 aluminum service entrance cable in 2 inch flexible metal conduit.

I was able to support the FMC by the eave purlin and run it down the corner column.

I plan to feed the FMC into the bottom of the main panel.

I’m still waiting on an a set of 2 inch FMC screw-in connectors to run it into the panel on each end, but there’s no rush, I have a lot more wiring to do.

I’m going to try and evaluate the performance of these units using an oscilloscope.

Early this morning I finally got around to taking a closer look at some EMI filters Adam scored for me when doing a job that involved relocating an MRI machine. They are medical-grade power filters that remove electromagnetic interference in the 150kHz to 18GHz range.
