When a 400A service upgrade is the right commercial move

New HVAC, kitchen loads, and EV readiness can outgrow legacy services — here is how we prove capacity before steel hits the roof.

Capacity studies start with real usage — not just connected load tables. We combine meter history, motor starts, and planned equipment with realistic diversity factors before recommending a service class change.

Utility coordination

Point of service upgrades touch transformers, meters, and sometimes street gear. We align outage windows with operations so refrigeration, security, and POS stay covered during changeovers.

Phased cutovers

Temporary feeders and careful sequencing keep tenants trading during upgrades. Documentation at each phase makes warranty and future tenant improvements simpler.
