PART 5

DISTRIBUTION BOARDS

1.0 General

The contractor shall provide distribut ion boards of the sheet metal type in

accordance w ith the requirements on the draw ings.

2.0 Size

All sw itchboards shall be of ample size to accommodate all the specif ied sw itchgear

and provide space for future sw itchgear. For every 6 (or part of 6) circuit breakers of

a kind on a sw itchboard, space for an addit ional circuit breaker of similar size shall be

allowed unless future space requirements are clearly specif ied the clearance between

adjoining sw itchgear or sw itchgear openings shall be as required by the equipment

suppliers.

3.0 External Dimensions

All external dimensions for sw itchboards shall be determined from f inal architect ‟s

draw ings and site measurements. If the clearances specif ied in paragraph 4.2 cannot

be adhered to as a result of restrict ing external dimensions, the Electrical Contractor

or Manufacturer shall obtain the opinion of t he Engineer before manufacturing the

sw itchboards.

4.0 Posit ions

The Electrical Contractor shall ascertain the exact posit ion of sw itchboards and shall

arrange t imeously for the installat ion of cable sleeves, openings in the structure, f lush

draw trays behind sw itchboards and supports over cable trenches.

5.0 Moisture and Vermin

All sw itchboards shall be rendered moisture, dust and vermin proof. During erect ion

of the installat ion the sw itchboard shall be protected against damage and penetrat ion

of moisture, dust or vermin.

6.0 Mounting Heights

In general f lush and surface mounted sw itchboards shall be mounted 1400 mm above

f inished f loor level – measured to the centre of the sw itchboard. The upper ends of

Where sw itchboards are to be built into 114 mm thick walls, expanded metal shall be

spotwelded to the rear of the bonding trays. The expanded metal shall protrude at

least 75 mm on each tray side to prevent plaster from cracking.

Ample knock-outs shall be provided in the top and bottom ends of each sw itchboard

tray to allow for the installat ion of conduits for the specif ied and future circuits.

Knock-outs shall be allowed for any size of specif ied conduit. Provision shall however,

dia. conduits at the bottom of each tray.

The architrave frame shall be of 1,6 mm thick sheet steel w ith bevelled edges. The

architrave frame shall accommodate the chassis, panels and doors. The architrave

shall overlap the bonding tray by at least 25 mm on each side. The architrave frame

shall be f ixed to the t ray in such a fashion to allow for depth adjustment and

irregularit ies of the wall.

Semi-f lush mounted sw itchboards shall be equipped w ith extension frames. Generally

the frame depths shall be 40 mm but may be altered to suit each applicat ion.

The chassis for mounting of sw itchgear and equipment in accordance w ith paragraph

A suitably st if fened panel manufactured of 2,0mm thick sheet steel shall be installed

in the architrave frame for f lush mounting of sw itchgear. This panel shall have

machine punched slots for housing the specif ied and future sw itchgear, instruments,

fuse holders, isolat ing sw itches, indicator lamps, etc. In exceptional cases contractors

w ill be allowed to protrude through the panel. Blanking plates shall be provided in

posit ions w here future sw itchgear w ill be installed.

The distance between the inside of the closed doors and the panel shall be not less

than 40 mm. No equipment may be mounted on the panel (face plate) unless it is

permanently hinged to the sw itchboard frame.

The panels for each sw itchboard shall be secured t o the architrave frame by means of

6 mm studs and chromium plated hexagonal domed nuts. Alternatively, the panel

may be secured to the architrave frame by means of tw o pins at the bottom and a

latch or lock at the top of the panel. Self tapping screws w ill not be allowed. Where

it is required that equipment be mounted on the panel, the panel shall be securely




3

hinged to the sw itchboard frame.

Two chromium-plated handles shall be provided on each front cover. The handles

shall be mounted at the top and bottom of each panel.

Where hinged panels are specif ied, the hinges shall be f ixed to the architrave frame

and the panel shall be secured by means of studs and hexagonal chromium plated nuts

or by means of a suitable lock or latch that can be operated w ith a screwdriver. The

panel shall be removable when it is in the open posit ion.

All sw itchboards shall be equipped w ith f lush f it t ing doors unless otherw ise specif ied

in the detailed specif icat ion. The doors shall be of a smooth f lat f inish suitably braced

to ensure st if fness and when in the closed posit ion, shall be f lush w ith the architrave

frame. The doors shall be of 1,6 mm sheet steel. The door w idth shall not exceed

600 mm. Doors exceeding 450 mm in w idth or height shall on all four sides be bent

inwards to ensure st if fness. The corners shall be welded and smoothed.

All sw itchboard doors shall be equipped w ith lockable handles and catches. Handles

consist ing of a pushbutton-and-handle combination w ith spring loaded latch or rotary

handle-and-catch combination shall be installed. Square key operated catches are not

acceptable unless specif ied in the Detailed Specif icat ion.

8.0 Construct ion of Surface Mounted Sw itchboards

NB: This section refers to surface mounted sub-sw itchboards and not to f loor

standing main sw itchboards in substat ions.

w ithout protrusions. The front tray sides shall be rounded w ith an edge of at least 20

mm to accommodate f lush doors.

Unless the depth of the sw itchboard is specif ied the dimensions shall be determined

according to the requirements.

The requirements of chassis, panels and doors shall be as specif ied for f lush mounted

sw itchboards. The doors shall be hinged and shall f it f lush in the frame in the closed

posit ion. Knock-outs shall not be provided unless specif ically called for.

9.0 Mounting of equipment

sides. For all freestanding sw itchboards and surface mounted sw itchboards w here the

main sw itch rat ing exceeds 100 amps (triple pole), space for w iring shall be provided

between the chassis and tray. This space shall also be adequate to pass the supply

cable behind the chassis to connect to the main sw itch w ithout making use of sharp

bends.

11.0 Grouping

The follow ing equipment shall be provided and grouped in logical fashion:

Main sw itch – to be installed at the top or bottom of the board w here the
