Procedure for Determination of Connected Load
1. Bulb / Fan
Actual rating or 60 Watt each,
if it is not possible to read the rating on the bulb / fan.
2. Tube Light
Actual rating or 40 Watt each
3. Light Plug
60 Watt up to three plugs and
extra 60 Watts for every three plugs or less.
b). Black & White
5. Power Plug
500 Watt up to three plugs and
extra 500 Watts for every three plugs or less.
7. Dessert Cooler
9. Air Conditioner 1 / 1.5 Ton
1500 Watt / 2200 Watt
10. Water lifting pump
180 Watt or 360 Watt (According
to Pump) or according to the equipment’s original rating (Name
plate & Specification).
any equipment is connected with plug point equipment’s load or plug
point rating whichever is maximum shall be taken. In such case,
load of plug point shall not be counted separately.
non-domestic light & fan consumer load of every bulb shall be
taken as 100 Watt.
load for Arc / induction furnace shall be worked out on the basis
of 600 KVA per ton of the capacity of the furnace.
higher rating of only one equipment shall be considered if both
Geyser and Air-conditioner (without heater) are installed. Only
heating or cooling use of these apparatus / loads shall be taken
into account as per prevailing season (i.e. 1st April to 30th
September for cooling use and 1st October to 31st March for heating
equipment which is under installation and not connected
electrically, equipment stored in warehouse / showrooms either as
spare or for sale is not to be considered as “connected load”.
the purpose of assessment in domestic connections, the water pump,
microwave ovens, washing machines, small domestic appliances shall
be considered for assessment for one hour working per day on 100 %
load factor. Appliances less than 200 watt shall not be taken into
Guidelines for Determination of
Load in case of Multi-storied Building/Colonies
domestic – 500 watt per 10 sq. meters of the constructed area or
requisitioned load, whichever is higher.
commercial – 1500 watt per 10 sq. meters of the constructed area or
requisitioned load, whichever is higher.
lift, water lifting pump, streetlight if any, corridor / campus
lighting and other common facilities, actual load shall be
constructed area calculated for (i) and (ii) above shall exclude
the constructed area arrived at in (iii).
diversity factors shall be considered for determining the maximum
Non Domestic Area: 0.75
Domestic Area: 0.5
building means a building having three or more stories excluding
car parking area, staircase area and balcony area, 50% of the area
shall be taken for calculating the built up/constructed area.
tank area and Chajja projection area shall not be considered for
calculating the built up/constructed area.
case the sanctioned plan indicates two or more buildings in the
same premises or the colony, they shall be clubbed together to
calculate built up/constructed area.
case only a portion of the building / colony is constructed as
against the entire building/colony sanctioned as per plan, and as
per the sanctioned plan the built-up area of building/colony is
more than 500 Sq. Mtr. or requisitioned load is 25 KW or more, then
in such cases space for transformer shall be given and power supply
shall be arranged on L.T. basis by installing a transformer in his
premises at applicant’s cost and also an undertaking shall be
obtained agreeing to convert to H.T. in future, when the
requisitioned load of the building/ area exceeds 50 KW .
the requisitioned load of the M.S. Building is 75 KW, the
transformer rated capacity shall be fixed to the nearest available
capacity i.e., 75 KW / 0.90PF= 84 KVA or 100KVA which is the
nearest higher Standard rating as per BIS. However if the
transformer capacity so calculated does not exceed 15 % of the
lower Standard rating, the Licensee can permit the erection of
lower capacity transformer provided the requisitioned load is
within the transformer capacity.
Licensee can provide higher capacity transformer if found necessary
to cater to other loads in the area, instead of the transformer of
capacity indicated above, the extra cost being met out by the
