Panels are built out of cold rolled and cold annealed steel sheets in 14 gauge for frames and 16 gauge basically for partitions. Panels are of welded non-bolted construction to facilitate specific tailor made layouts. Panels with angle iron framework can also be offered on specific requests.
All sheet steel undergo a phosphating treatment process of degreasing, derusting, phosphating and passivation in a seven tank process. Powder coating is adopted as a standard and unless otherwise specified, panels are painted in RAL 7032 Siemens grey shade.
On specific requests, panels can also be supplied in standardised modular enclosures Rittal. MPP makes.


The busbars are liberally rated and proper design factors for higher ambients, enclosure conditions, number of busbars, short time current capability etc., are all considered while arriving at the sizing.
PVC colour coded heat shrinkable sleeves are generally provided as a standard practice. In certain cases, busbars are painted with matt black with phase identification to allow for higher heat dissipation.
In order to ensure proper heat transfer of overlapped joints, precautions by way of cleaning, greasing, usage of high- tension bolts, with tightening by torque wrench are adopted.
Busbars shall generally be of electrical grade Aluminium with 99.5% purity.
Alternatively, Copper busbars EC grade with 99.9% purity can also be provided on clients request.


Busbar supports shall be of SMC or DMC. Finger type supports are adopted for main horizontal and vertical busbars to provide the requisite strength and rigidity to withstand short circuits.
Epoxy moulded conical supports are provided for feeder lines.
A proper spacing and selection of the supports ensure that panels withstand the appropriate or specified short circuit levels.


Panels are designed to have adequate clearances between live parts and between live parts to earth. These are generally far higher than that specified in the relevant British Standards.
In many cases, due to constraints arising out of inadequate clearances available in certain components, FRP barriers are provided to enhance safety.
Additionally, to increase safety levels specially with regard to operating and maintenance personnel, hylam barriers are liberally used to prevent any inadvertent and accidental contact with live parts, for e.g. at cable terminations, feeder components, etc.,


In case of feeder ratings above 63 Amps, terminations are by means of staggered busbars to prevent fouling of phase and neutral cores. Up to and including 63 Amps. Elmex melamine stud type terminal blocks are used.
Terminal blocks are located in the cable alleys wherever provided and wiring from the feeder units to the terminal blocks are carried out by single core flexible PVC copper cables.
Separate control terminal blocks located away from the power terminals for motor controls facilitate proper interconnecting control cabling to local stations and drive motors.


Internal wiring within the panels, colour coding, etc., both for the mains and auxiliary wiring shall generally be as per IS:375 Standards.
Wiring is properly identified by ferrules at both ends. The wiring is carried out neatly and for longer lengths, largely run in PVC slotted cable troughs in such a way that it does not hinder maintenance.

Wiring terminals are of crimped type. Wiring is carried out with 1.1 kv grade flexible copper cables - 2.5 sq mm and 1.5 sq mm for CT and PT secondary circuits respectively.
FRLS or heat resistant cables are also offered against specific requirements.


The panels are well laid out with proper compartmentalisation and segregation for feeders, cable terminations, metering and protection, busbars, cable alleys, etc., The layouts are such that damages if any caused due to short circuits are localised and contained.
The power and control lines run neatly, away from each other. All control components-with proper identification to its circuitry-are so mounted to render easy maintenance and accessibility.
Conditions as prevailing at site also receive due consideration while planning the layouts. All necessary interlocks both for the feeder component itself and also between the components and the panel are provided.
The operational interlocks and sequences are tailor built to suit individual needs.
An earth bus of adequate size-either Aluminium or Copper-is run throughout the length of the panels and directly mounted on to the panel frames. The earth terminals of components are connected to this earth bus. The earth bus generally protrudes at both the ends to facilitate earthing connections.
A braided copper flexible connects the hinged doors with the fixed part.
