Adding Additional Load to ASCO D07ATS030100N5XC, 31BG, 40DR, 150A Transfer Switch

[GRD_DoubleE]

Hi everyone,

I’m a relatively new electrical engineer out of college and am working on a project involving an ASCO 7000 Series automatic transfer switch (ATS) that was already installed before I joined the company. The existing ATS is currently set up to transfer power to a panel during emergencies, switching from the normal power source to a backup generator. My task is to add additional power panels/breaker panels to this setup.

From what I’ve reviewed in the wiring diagrams, it seems like this ATS is designed to handle one 3-phase load at a time. Does this mean the ATS is intended to supply power to a single load, which would then distribute power downstream to other panels or equipment? Or is there a way to configure it to directly handle multiple loads?

Alternatively, the solution might just be installing additional ATS units? I’d appreciate any insights or advice on how to approach this! Thanks!
