Upgrade & Retrofit

NCE provide a comprehensive package to ensure the critical uptime for all types of switchgear. 


How we can help?

NCE's offer fully type tested designs to the latest international standards, Inc, IEC, ANSI, CAS and Marine Classification Society Rules. NCE Service division can apply all of these services at any stage of the switchgears life cycle, with a full and comprehensive report including detailed analysis and conclusions for the most cost effective approach to maximising uptime, MTBF, safety and security with scheduled interruptions to supply.

  • Extensive electrical test/commissioning expertise of low/medium voltage switchgear.

  • AC/DC drive system upgrades.

  • Generator/Transformer systems.

  • Protection upgrades for digital control schemes.

Retrofit Conversion
Retrofit Conversions

With extensive experience of retrofit conversions NCE Service division can provide full compatibility retrofitting current ACB's for legacy ACB's.

  • Simple Relays

  • Meters

  • MCCB's

  • Up Rating Busbars


NCE Service can provide a one stop shop. Legacy ACB's can be retrofitted with any current manufacturer of ACB's, using NCE Service division's unique designs.

NCE Service division can offer a total solution, from detailed analysis to (IS09001-2008) 3D design, full in house manufacture, assembly, and test, with a dedicated site team providing peace of mind installation and commissioning. 

We have a number of customers who rely on NCE to upgrade existing installations that are nearing the end of useful life. These are typically from the Oil & Whisky Industries where they may have an old DOL starter that needs changed to a VSD but must be powered from the same area.We are happy to visit and recommend solutions.

Arc Mitigation
Arc Mitigation Solutions

Whether you require arc fault monitoring using fibre optic light detection or permanent Infrared Continuous Thermal Monitoring of Critical Electrical LV/MV Switchgear Connections.


Hotspot Detection can be applied to detect electrical failure, NCE has an arc early warning and mitigation solution to suit your needs to lengthen the life of non certified switchgear, regardless of original switchgear manufacturer.

NCE can offer Ultra-Fast Earthing Switch solutions using fast acting detection and extinction electronic primary switching, as new, or as retrofit assemblies for: 

  • Site installation into existing non arc type tested assemblies > 690Vac 85kA / > 11kV 50kA to mitigate arc propagation and equipment damage due to overheating

  • Ageing of insulation and mechanical wear

  • Loose joints

  • Moisture, Dirt and Corrosion

  • Over-voltage and overheating problems.
