A downloadable specification form is available to initiate the electrical engineering design of all Lucy Zodion type feeder pillars. All electrical work should be conducted in accordance with the Electricity at Work Regulations All feeder pillar installations should be designed, tested and installed in accordance with the IET Wiring Regulations BS Requirements for Electrical Installations — any other local regulations in force at the time should be observed. Pre-wired Electrical Distribution Feeder Pillars.

Prewired pillars can be mounted either on the supplied metal root, which is buried in the ground see Figure 1 below, or bolted directly to a concrete base. Figure 2 below is supplied for guidance only and a suitably qualified civil engineer should always be consulted to determine the exact method of installation. It is crucial that the unit is equipped with suitable drainage. Lucy Zodion recommend using a mm drain pipe with positive drainage to the main sewer.

While the low voltage installation is IP67 rated, incorrectly replaced caps and covers allow opportunity for ingress of water and long term exposure can permanently damage to internal components of the feeder pillar. Westminster Retractable feeder pillars are supplied with recess pockets of a suitable depth for the proposed infill material.

This depth is specified at order. Infill material must be installed flush with the surface and around the lock cover and hinges. Some means is necessary to hold the material in place when the feeder pillar is in the vertical, raised position, e. A copy of the test documentation, along with a schematic drawing of the Lucy Zodion supplied equipment, is supplied with the pillar. It is assumed that electrical installation is conducted by a suitably qualified and skilled person and the following information is for general guidance only.

The cable may be wired and connected directly into the main switch disconnect, wired through a cable spreader chamber or wired into a terminal enclosure depending on the size of the incoming cable. The provision for terminating incoming cable can be determined from the drawings that accompany the feeder pillar or identification of the parts on the pillar.

As feeder pillars are often located remotely from the electrical equipment they supply the outgoing cable sizes often have a large cross-sectional-area for the current rating and cannot be terminated directly into the pillar equipment. For large outgoing CSA cable sizes suitable cable termination equipment, terminal studs or blocks, are supplied pre-wired into a terminal box.

Incoming and outgoing cables should be wired into these terminals, if supplied, to avoid overcrowding on the main distribution board or where equipment is unable to accept cables of the size specified. Suitable space has been left for the cable glanding of outgoing unarmoured or armoured cables, in the form of cable gland plates on the distribution or terminal enclosure, a cable spreader chamber or a horizontal length of galvanised trunking.

The pillar and all accessible metal parts within the pillar and all CPC earth in pre-wired equipment are equipotentially bonded to the earth block. Retractable feeder pillars are supplied with a terminal enclosure mounted in the fixed base of the unit and attached to the outgoing circuits via a pre-installed flexible cable. Once cable terminals have been connected and appropriate tests conducted the supplied Magic Gel should be used. In all cases the installation must be connected to a suitable earth supply.

The installer should check the earth loop impedance of the installation as this cannot be verified at the factory. Unsupported lengths of cable should be kept to a minimum. Where there is more than one cable they shall be connected along their length at not more than 1 metre intervals. It is essential that the supply is isolated before any covers are removed from enclosures. For work to be carried out on the incoming terminal board or switch disconnect it is necessary to isolate the supply coming into the feeder pillar.

Switch disconnect isolates the main incoming supply from the rest of the equipment in the feeder pillar. In cases where a switched neutral is installed the live phases always cut out first when the switch is disconnected. All main isolators are capable of being locked off to allow safe working on the equipment. It is essential to lock-off the device when working remotely from the pillar, for example double sided or double length feeder pillars, or equipment being supplied from the pillar.

Switch disconnects may be Fuse Combination Units which are suitable for making, breaking and isolation. The correct fuse for the device is installed prior to the unit leaving the Lucy Zodion factory. Should the fuse require replacement it is essential that the correct rating of BS88 HRC fuse is fitted.

The switch fuse can be locked-off to isolate the rest of the system from the incoming electrical power supply. In cases where the main board is group switched an auxiliary board will be supplied to supply 24 hour power the pillar equipment e. Socket outlets for use by normal persons are supplied as standard via an overload protected, residual current device, e.

Periodic testing of this device is required via the test button on the unit. Group switch controls a group of equipment, typically street lighting installations, via a control system, such as a photocell or timer.

Be sure to isolate a group switch from the incomer on the 24 Hour board, as group switches are remotely controlled they can go live at any time. Group switch control — the group switch can be controlled by a timer, photocell or an override. A typical installation with a group switch would control street lighting. Residual current devices all socket outlets are protected by a residual current device as well as suitable overload protection.

All residual current devices should be tested periodically and at least every six months. Surge protection devices are installed, if specified, to suit the earth system indicated by the customer e.
