FAQ
Common questions
How long does a utility service upgrade with ConEdison typically take?+
Utility upgrades involve engineering review, layout approval, transformer vault prep, and cutover scheduling. We assist in expediting submittals to streamline utility lead times.
What is the difference between ATS and Manual Transfer Switches?+
An Automatic Transfer Switch (ATS) monitors utility power continuously and triggers generator startup automatically upon outage detection. Manual switches require physical operation on-site.
Why is NETA testing required for main switchgear?+
NETA acceptance testing ensures switchgear has zero manufacturing defects, proper busbar torque, and dielectric strength before applying utility power.
