Kohler ZCM Bypass, Isolation Transfer Switches Installation Checklist (tp6534)

In commercial buildings, data centers, and plants where power has to stay on during utility failures, these Kohler ZCM bypass/isolation transfer switches sit between the generator and your loads, often in tight electrical rooms. This checklist helps you install and verify the switch wiring and setup so it transfers cleanly without backfeeding or dropping critical circuits. I’d keep this on hand when bringing a new switch online—say you’ve just landed all the feeders and control wiring and need to confirm everything is landed, torqued, and labeled before you energize and attempt a test transfer.

Applications & Use Cases

• Walk through a step‑by‑step installation check before first energizing the transfer switch.
• Verify bypass and isolation functions are correctly set up so you can safely service the ATS later.
• Trace and confirm control wiring and sensing circuits to avoid misoperation during automatic transfer.
• Inspect grounding, bonding, and enclosure terminations so the installation meets typical code and site standards.
• Use as a final sign‑off sheet for commissioning, so everyone knows the switch was checked the same way each time.

FAQ

Q: Can I use this checklist on a tablet at the jobsite?

A: Yes, it works well digitally; you can zoom in, tick off items as you go, and keep it with your other project files.

Q: Should I still print a copy for my records?

A: It’s a good idea—many techs keep a signed, dated printout in the switchgear folder as proof of what was verified at startup.

Safety Note

Always de‑energize, lock out, and verify absence of voltage before opening or working inside any transfer switch.
