A feeder pillar (also referred to as an influence box, distribution pillar, or feeder pillar box) maybe a cabinet won't to house electrical equipment. Feeder pillars act as a central circuit that controls and distributes electricity to outgoing circuits downstream to the feeder pillar. This setup provides each circuit protection, alongside the capacity to be easily controlled.

Similar to a junction box, a feeder postbox protects people from coming into contact with live wires, also as protecting wires from dust and dampness.

Electrical feeder pillars are mounted on the road and are wont to control the electrical supply to houses during a neighborhood. A feeder pillar is another word for a cutout enclosure or other electrical enclosure that's used as a part of an underground electrical distribution system.

You may have inadvertently seen electrical feeder pillars driving around without taking much notice. they're typically found near:

Airports
Highways
Rail
Retail & Leisure
Substations
Street Lighting
Temporary Generator Power Hook Ups

Feeder Pillar Components

A feeder pillar seems like an enormous steel wardrobe. The outer body of a feeder pillar is usually around 2 millimeters thick.

Electrical feeder pillars are typically manufactured in aluminum sheets or electro-galvanized/galvanized steel sheets. Double-wall and single wall constructions are available during a 4/6/8 distribution.

These include ammeters, selector switches, whole house surge protectors, service fuses, and instrument panels with voltmeters. the planning, structures, and build are suitable for all types of lighting applications. the whole feeder pillar unit is mounted on top of a steel base.

Traditional Feeder Pillars

The traditional feeder pillar design involved a break, supporting busbars, a pole-operated disconnector (isolator) for the incoming circuit, and outgoing fuseways which are mounted in insulated carriers.

There are a few downsides to the present traditional feeder pillar design:

Easy to form accidental contact with live and exposed conductors
Switching of circuits is administered by the insertion and removal of the fuse handles (a potentially hazardous operation)

The close proximity of the terminals to adjacent and unscreened conductors makes cabling one circuit very difficult

As safety standards have increased over the years, these flaws within the traditional feeder pillar design have caused them to be phased call in favor of more modern sorts of feeder pillars. Although these modern sorts of feeder pillars are much safer than traditional designs, good safety practices should still be followed, including wearing good electrical gloves and anti-fog safety glasses.

Types of Feeder Pillars

Feeder pillar panels can come as custom manufactured or standard empty enclosures. Here are the foremost common electrical feeder pillars that are available:

Rail Feeder Pillars

Rail feeder pillars are non-conductive and are available in an outside location or station installments. It eliminates the danger of touch voltages in electrified rail areas. These pillars can have PADS approved Network Rail equipment such as:

Switchgear
DC Immune RCD
DNO Service Hands
Isolation Transformers
CT Chamber & Member
Cut-Outs & Isolators
LV Feeder Pillars

Low voltage feeder pillars (LV feeder pillars) are feeder pillar panels that operate at a “Low Voltage” (LV), where “Low Voltage” is defined by the International Electrotechnical Commission (IEC) as a supply system voltage within the range 50 to 1000 V AC or 120 to 1500 V DC (if you’re unsure of your operating voltage, you'll easily check this with an honest multimeter).

Electrical distribution pillars give LV power connections for single units or complex developments within the commercial and residential sectors.

LV feeder pillars are used for utility substation, M&E building services, hazardous area industries, and renewable energy. Highway pillars are used for CCTV, traffic signals, street lighting power, motorway communications, and control and distribution.

Feeder Pillar Design Considerations
Installation
Feeder pillars are installed by professional electricians who are experienced, trained, and qualified. and that they must follow the local municipality’s requirements in health and safety in lighting conditions in any location.

Thus, only approved pillars from manufacturers should be installed to make sure full compliance with local authorities on electrical safety and lighting. There is often a label of approval by the proper authorities on each pillar which will be installed on any premise, whether its outside or inside the property.

The best positions should be in areas that avoid serious dangers to customers around the area. Space should be clutter-free, therefore the electricians can work on repair safely and simply without causing potential risk to consumers. The feeder pillar should be lit, although if that’s impossible electricians can always wear headlamps while working.

Functionality

Feeder pillars have a definite value of their presence in any environment to make sure that the fuse is secured from the property to avoid any electrical issues.

Although the feeder might appear as a metal box storing up circuity wires and coaxial cables, they create a crucial protection platform on any property. They function to carry circuitry safely if there’s a requirement to upgrade the circuit box at the designated area. Having an honest feeder pillar isn't enough though to form sure everything is protected, and you ought to always make sure that you’re using one among the simplest coaxial cables money can purchase (as they're not very expensive).

An experienced electrician will recommend the proper feeder box to carry all of the circuitry for better lighting efficiency. the proper feeder helps manage an enormous power supply that safely goes through the wires with the fuses labeled for straightforward identification. If you would like help with this, an honest circuit tracer can assist you in quickly identify breakers and fuses and tracing wires behind walls.

Simple Minded Operation

Feeder pillars have an easy connection interface that permits for quick connection of maintenance or emergency power source. The feeders are fitted with terminals that have self-snapping fuse screws to stay the tightening torque.

The power supply for lighting and internal circuits are directly provided by the pillar. Thus, making their operation simple and straightforward for electricians to utilize supported their location.

Design and Robustness

A good feeder pillar should have a smooth and sleek design. It should have improved user safety via large thermostat insulated fittings. thanks to its rigidity, its insulation material provides more robustness; making it ready to survive harsh storms and other tough conditions. confirm to use one among the simplest insulation resistance testers if you would like to live the insulation resistance.
