Extensions & Retrofits

Extending equipment life by adding ways, metering, protection and control

Extensions & Retrofits

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

General arrangement and schematic drawings for approval
Updated schedules, labelling and as-built documentation
Test results for the extended or retrofitted sections
Shutdown method statement and staged switching plan

Information To Get Started

Existing board photographs, rating plate and internal layout

New load requirement and preferred device range

Available shutdown window and phasing constraints

Metering or monitoring requirements to be added

No spare ways left for a new machine, tenancy or feeder

Metering needed for tenant recharge or energy reporting

Add capacity with a clear view of the existing installation.

Information to send

Existing board drawings and nameplates
Demand measurements and proposed loads
Spare ways and shutdown window

Scope to agree

Capacity and interface review
Retrofit options
Staged changeover plan

What changes the selection?

Equipment duty, installation conditions, available fault current, control interfaces and expansion plans all affect the specification. Agree the required drawings, tests and handover records before placing an order.

Specify the whole working system.

Start with the equipment duty. Add the control, protection and measurement functions that your project needs; these are options to review, not a pre-approved assembly.
