Switchboard Enclosures for Tight MCC Plant Rooms
Choosing an EV Feeder Pillar for DNO Supply Upgrades
Engineers face many decisions when they plan EV charging installations. They often wonder how much space the feeder pillar needs for future utility upgrades. They also ask about room for metering and extra switchgear. At A&T Enclosures, our team works with projects that connect directly to DNO supplies. We build EV feeder pillars that handle these needs from the start.
We design every EV feeder pillar with DNO connections in mind. The pillar serves as the main point where the distribution network operator brings power into the site. It distributes that power safely to multiple EV charge points. Proper planning at this stage prevents costly changes later. We make sure the enclosure supports the incoming supply cables and provides clear access for DNO staff.
Space Planning for Long-Term Use
Space inside the feeder pillar matters more than many realise. We allocate dedicated areas for current equipment and for items that may arrive later. Our designs feature modular layouts. This approach lets us fit busbars, circuit breakers, and monitoring devices in an organised way.
We use raised plinths in many outdoor models. These plinths protect against water ingress and give installers better access to the base. We also provide options for DIN rail mounting and gear plates. These features make it simple to add control devices as the site expands. Engineers appreciate the flexibility because it matches real-world project timelines.
Switchgear Considerations
Switchgear forms the heart of any reliable EV feeder pillar. We support low-voltage distribution up to 3200A. This rating covers most commercial and public charging installations. We can supply the pillar as steelwork only so teams can fit their preferred switchgear. Our experienced technicians also install free-issued equipment when requested.
We build secondary barriers behind the main doors. These barriers improve safety for anyone who works inside the unit. We follow BS EN 61439-2 standards for the form of separation. This gives users clear protection while they perform maintenance or inspections.
Future-Proofing Checklist
We recommend that engineers run through a short checklist before they finalise the feeder pillar specification.
Consider the maximum expected load over the next five to ten years. Factor in any planned increase in charge points. Check whether the DNO may require separate metering for different phases or tenants. Review access requirements for maintenance and emergency isolation. Think about cable entry points and how they will handle additional runs. Confirm the required IP rating for the installation environment.
We help teams complete this checklist during the design phase. Our engineers review drawings and suggest adjustments that add capacity without increasing the overall footprint too much. This collaborative process leads to enclosures that last and adapt.
How A&T Builds Bespoke Feeder Pillars
At A&T Enclosures, we handle every stage of production in our facility. Our engineers translate project requirements into precise fabrication instructions. This control keeps quality consistent and lead times reliable.
We test enclosures to relevant IEC and British standards. We verify ingress protection, mechanical strength, and electrical safety. Every EV feeder pillar leaves our site ready for installation. We also offer a wide choice of colours and finishes so the unit blends with its surroundings.
Our experience with feeder pillars and EV pillars spans many sectors. We have supplied units for workplace charging, public car parks, and retail developments. Each project teaches us more about the practical challenges engineers face on site. We apply those lessons to every new design.
We build EV feeder pillars that straightforwardly support DNO supply upgrades. The enclosures give teams the room and features they need for current work and future growth.
If your next project involves an EV charging installation with DNO connections, consider how the feeder pillar will serve both today and tomorrow.
