In addition to all General Guidelines for booth construction mentioned above, exhibitors with Built-up booths must follow these additional electrical guidelines:
-
The booth contractors undertaking lighting work shall possess valid electrical license, which is subject to inspection by the organiser.
-
The load ≤ 4 kW shall be fed through single phase electrical supply at 230V AC ± 6 % and load >4kW shall be fed through 3 Phase electrical Supply at 415V AC ± 6 % The supply Frequency will be 50Hz ± 3%.
-
The exhibitor requiring supply at voltage level other than above shall make necessary arrangement for the level matching equipment such as transformer, voltage stabilizer, inverter etc. to match the supply voltage level to their load.
- For entire booth lighting the contractors shall use BIS marked PVC insulated 650/1100 V copper conductor wire.
- All switch boards shall conform to BIS & to Indian Electricity Act (amended).
-
For lighting circuit, the minimum wire size shall be 1.5/2.5 sq.mm PVC insulated 650V grade FRLS copper wire. For 16A power point, the minimum wire
size shall be 4sq.mm PVC insulated 650V grade FRLS copper wire. The IR value of cable used shall not be less than 1MΩ when measured with 500V DC
megger.
-
The contractor shall lay main earth wire of size not less than phase wire for their booth from point of supply (MCB Box) conforming to IS: 3043-1987. The earth wires shall be connected to the main earth firmly. The voltage between neutral & earth shall not exceed 10V.
-
It is mandatory to use only reputed make wires like Polycab, KEI, Anchor etc and MCB/RCCB like Legrand, Siemens, ABB, Schneider for the electrical installation.
-
Wherever 3 phase connection is requested, the load shall be evenly distributed on all three phase.
-
In case any material used by the contractor is found to be of inferior or sub-standard quality, the contractor shall be responsible for replacing the same without any loss of time as per the quality mutually agreed and mentioned above.
-
Exhibitor shall ensure that, the contractor shall carry out all electrical works in the booth area as per Indian Electricity rules 2005
-
It is recommended to make use of low loss/ low heating choke manufactured as per IS and of reputed makes like Philips, Crompton, Bajaj, Wipro or equivalent.
-
The contractor shall control maximum 8 lights or 800Watts from single point.
-
Joint to the wires in any place is unacceptable. However, good quality connectors of adequate rating properly covered can be used.
-
Use of 3-pin top / industrial top shall be made to take supply from sockets. It is strictly prohibited to insert wires directly into socket for drawing supply.
-
Exhibitors must install separate and independent MCBs/MCCBs/RCCB of appropriate rating for their individual machines.
-
Exhibitors requesting for 3-phase supply shall draw single phase power for lighting purpose from 3-phase supply outlet using double pole MCBs. The double pole MCB/RCCB shall be arranged by the exhibitor.
-
The electrical supply will be released only after completion of wiring work conforming to the Indian standards & codes of wiring and to the satisfaction of Electrical consultant.
-
Exhibitors may contact the Electrical Consultant at venue office for any technical queries.
-
It is recommended that exhibitor uses official Electrical Contractor to avoid any dispute arising in consumption on account of wiring/ loading etc.
