The document provides updates from the ILP Technical Committee on several current projects: 1. It discusses the PLG01 CMS project which involves developing functional benefits, system components, architecture, implementation issues, and delivery process for a CMS system. 2. It provides an update on the TR22 project to review and update guidance on lighting supports, including developing a robust condition assessment methodology. 3. It outlines a new guidance document being developed on electrical street furniture which will address safety, installation, and operational considerations for equipment like EV chargers and market stalls being installed on highways.

8. Introduction
• Growing requirement for electrical equipment in the public realm
– Electric vehicle charge points
– Market trader pillars
– Event supplies
– Information points
– Bike hire points
– SMART Technologies points
• Raise the awareness of the electrical safety considerations and
requirements
• Walk through the processes, requirements, risks to be considered and
implemented
• Does not replace the need for technical underpinning knowledge and
competency
• Does not duplicate existing Standards & guidance
• Owner, operator and user requirements

9. Benefits of such installations
• The provision of electrical supplies has many
community benefits
– Enhanced economic growth
– Benefits through investment in the area
– Provision of a service
– Green agenda
– Improved information sharing
• Highway Authority must act reasonably
• Be sensible in what is offered

10. Considerations
• Considerations prior to installation
• Physical installation requirements
• Electrical considerations
– Network capacity
• User requirements
• Risks
• Service charges
• Operation and maintenance
• Provision, maintenance and operation of
electrical equipment in the public realm for
third party use
• A Highway Authority should act reasonably
• CDM Regulations
• Where does ownership end?
– Point of supply (socket)
– Provision of connecting cables
– Testing, maintenance and operation
– Enforcing rules / operational procedures on
users

11. Electrical requirements
• Determination of the earthing requirements
• Energy Networks Association Engineering
Recommendation G12 A PME termination
should not be offered
• TT system with an RCD (BS
7671.722.531.2.101)
• Excepting lighting columns & signs all electrical
equipment should have a TT connection
• Requires adequate client earthing
arrangements
• Earth electrode
– Sequence of earth mats or rods below
600mm
– Resistance < 200Ω
– Consideration for future utilities operations
– Supported by a time delay or ‘S’ type RCD
not exceeding 300mA
– Column roots are not suitable
– Looped cable networks ≥ 3 items require
an earth electrode at the supply point and
end of circuit

12. Electrical requirements
• Adjacent equipment
– Consideration for any electrical equipment within 2m of the proposed equipment
– Such equipment should be on the same electrical phase and from the same
distribution point
– All equipment should be on the same type of supply i.e. TT
– Columns with combined charge points or similar should be on TT supplies

13. Charge points incorporated into existing equipment
• Greater demand for charge points to be
installed
• Especially where vehicles are parked overnight
in residential areas
• Not practical or safe for the owner to run a link
cable from their house
• Residents are making requests for on street
charging stations
• Where electrical street furniture is located
towards the front of any footway it makes
sense to consider how a change point may be
located within it
• The general approach for standalone charge
points is for a TT supply
• Customer (authority) providing their own
earthing system
• Column root consideration <100Ω
• Load requirement can be addressed by only
providing a trickle charging facility but the
earth resistance limitation does require careful
consideration
• Energy in these instances is measured through
a meter incorporated into the link lead
charging cable

14. Operation and maintenance
• Authorised user agreements
• User made aware if their responsibilities
• License agreements / conditions
• Access to supply point
• Trailing cables
• Wet weather conditions
• Earthing considerations
• Electrical load @ equipment connected to
supply
• Testing & inspection requirements
• Owner monitoring
• Fault reporting / misuse action
• After use requirements
