I have materials for panels. I have 4 x SqD NQ 225A, MLO, 42 space 120/240 volt primary service panels in stock. $4500. I have 2 x 100A, MLO, 18 space subpanels. I have stock to make 20 panels. Then I am out of parts.
I have waited a year to refresh my stock but I don’t know if SqD will ever make the solid copper mechanical lugs and neutral terminal bars anymore. What I have been told is they are a year into backlog fulfilling Data Centers switchboard orders. They don’t want to be bothered with small ticket items. The same holds true for Eaton, Siemen and GE.
These panels require a meter with 200A CB disconnect built in. Or a 200A stand alone CB disconnect would need to be nipple to the side of the panel as a protective disconnect.
I have one Benjamin Electric 225A, 24 space single phase 120 volt only panel that is designed to distribute power from a 100A Torus isolation transformer. This panel is on hold.
