Westminster In-Ground Feeder Pillars
The Lucy Zodion Westminster retractable feeder pillar offers a secure and space-saving solution for temporary or semi-permanent low voltage power access. Engineered from galvanised steel with an IP67-rated enclosure, the pillar deploys from ground to socket in under 60 seconds and retracts completely when not in use—ideal for high footfall or publicly visible environments.
These in-ground electrical feeder pillars are specified with earth leakage protection, overload safeguards, and metering or data access where required. Popular in applications like markets, event spaces, transport hubs and shopping centres, the Westminster range delivers flexibility and safety in equal measure.
- Versatile: Designed for power, metering and data in commercial and civic environments.
- Discreet: Flush-fitting top with 50mm recess allows for surface matching and hidden installation.
- Robust: IP67 ingress protection, stainless steel hinges, and tamper-proof locking.
- Safe: Built to BS7671 and BSEN 61439 standards for safe operation in public spaces.

Public & Street Lighting Feeder Pillars
Our street lighting feeder pillars are manufactured from hot-dip galvanised steel to IEC60947 standards and designed to protect and control LV power distribution networks. These enclosures support metered and unmetered public lighting installations with 3-phase configurations and HRC type fuses for short-circuit protection.
Custom Feeder Pillars for Critical Infrastructure
Thorne & Derrick works in partnership with Lucy Zodion to develop custom-built feeder pillars for NHS trusts, rail projects, and utility networks. These pillars are fabricated with IP65-rated galvanised steel enclosures and integrated foundations, enabling safe connection and termination of 3- and 4-core XLPE SWA LSF or PVC cables (BS5467 / BS6724).
In this example for an NHS facility, single and double door feeder pillars were configured to distribute power from LV switchboards and substations to site-wide systems.
Another example includes a pre-wired feeder pillar built for a TransPennine Express train care facility. This 3mm thick galvanised enclosure includes a removable root section and bitumen base coat, housing a 250A busbar with 3P+N switch disconnect. All internal wiring and galvanised trunking complies with BS5467 660V/1000V.
Rail Feeder Pillars & Network Rail Approved Solutions
We supply GRP feeder pillars for rail and trackside installations, engineered for low-maintenance, corrosion resistance, and safety in electrified zones. GRP feeder pillars, cabinets and kiosks are non-conductive and eliminate the risk of dangerous touch voltages in public or PADS-specified areas.
These Network Rail approved feeder pillars can be equipped with:
- DNO service heads
- Isolation transformers
- DC immune RCDs
- Cut-outs, isolators & CT chambers
- Switchgear and metering panels
Featured here is a Lucy Fortress F30 double-door feeder pillar with 315A MEM fuse switch disconnect, mounted to an 18mm treated plywood backboard. Optional features include integral lighting, heater, photocell control, and timed keyswitches.
Each pillar is constructed from 3mm thick steel, finished with bitumen-coated root sections and tri-head locking mechanisms for anti-vandal protection.
Feeder Pillar Cabinets for EV Charging
Image: Siemens – Electrical feeder pillar supporting a three-phase EV charging installation
Feeder pillar cabinets play a critical role in delivering safe, low voltage power distribution to electric vehicle (EV) charging stations. These pillars are typically supplied with a 3-phase DNO (Distribution Network Operator) connection and house protective switchgear such as RCDs and MCBs to guard against overloads and electrical faults.
The internal components are fully bonded to earth to meet safety standards and ensure reliable operation of the EV charging pillars. Power is routed underground via cable duct to the charge unit, with enclosures designed to IP-rated standards for external use. These cabinets are ideal for public and private EV infrastructure including forecourts, commercial fleets, and local authority car parks.
Important: As this equipment handles live mains voltage, installation and maintenance should only be performed by qualified electricians wearing appropriate arc flash protective clothing.
Standard Feeder Pillar Construction
Our feeder pillars are manufactured to the highest industry standards, combining durability, weather resistance, and security for electrical power distribution. Each electrical feeder pillar is designed to meet outdoor installation requirements and is suitable for applications such as street lighting, EV charging, and public infrastructure projects.

Feeder Pillars – Frequently Asked Questions
Q: What is the best feeder pillar for outdoor electrical installations?
A: Galvanised steel or GRP feeder pillars are typically best for outdoor use due to their weather resistance and durability. However, the ideal choice depends on your site’s environmental conditions and electrical load requirements.
Q: How do I choose the right size and specification for a feeder pillar?
A: It’s based on your current rating, switchgear type, and how many circuits you need to terminate. Internal space for wiring and future expansion should also be considered — but many specifiers miss a few critical layout factors.
Q: Are stainless steel or GRP feeder pillars better for long-term use?
A: Stainless steel offers strength and vandal resistance, while GRP is ideal for coastal or corrosive environments due to its non-conductive, rust-proof properties. Which one performs better long-term depends on your application and exposure levels.
