LV Assemblies
We provide a wide range of bespoke LV assembly solutions, offering impressive flexibility to an extensive list of clients.
Intelligent, collaborative design
Using intelligent 2D electrical design software and 3D CAD systems, our LV assembly solutions take into consideration important environmental and in-service requirements. For example, the space needed to gland and terminate cables, and safe access for maintenance personnel to carry out routine tasks and modifications (through internal separation).
3D BIM designs allow us to work collaboratively with multiple stakeholders on aspects such as clash detection and defining access routes, allowing clients and end-users to visualise how proposed designs will integrate with the requirements of the building in which the LV assemblies are to be installed.
LV solutions
We will maximise the value of your assets by providing effective, efficient, and safely controlled operation while minimising your whole-life costs. It’s why we’re the supplier of choice for so many blue-chip companies.
M Group is a leading supplier of LV assemblies including packaged sub-stations and main/sub-main LV switchboards and motor control centres (MCCs) and control panels.
Our LV solutions are manufactured and tested within our 2500m² workshop, using intelligent design and advanced manufacturing processes. This means you get quality-assured products with fast build times.
We offer full turnkey projects including site installation, extended warranty periods, on-site support and after sales service from a team of experienced engineers.
LV assemblies – design-verified for peace of mind
Our LV assembly solutions offer current ratings up to 6300A in enclosures with various ratings of IP code, incorporating busbar systems with short-time withstand ratings of 25kA, 50kA, 80kA and 100kA for 1 second, each tested and design-verified to BS EN 61439-2 (power switchgear and controlgear assemblies).
All of our LV assembly designs are verified across the full range of required technical characteristics, including temperature-rise limits and electromagnetic compatibility. This is achieved through ongoing, third-party accredited independent testing at dedicated laboratories across the UK and Europe.
Technical characteristics requiring design verification by other means are completed in-house by our LV design engineers, in line with our rigorous conformity assessment and marking procedures. With over 30 years of certified designs, you can rest assured in the safety of our extensive range of LV assemblies.
