Extensions & Retrofits

Overview

Extensions and retrofits add outgoing ways, metering, surge protection, power quality equipment or control upgrades to a board that is otherwise sound.

Fault level, busbar capacity, temperature rise and forms of separation are reviewed first, so the extension is engineered rather than squeezed in.

What We Cover

Fault level, busbar and heat rise verification before design
Additional outgoing ways, sections and cable entry provisions
Retrofit of metering, surge protection and power quality equipment
Site installation, testing and re-commissioning

What You Receive
