120 sq ft are require 1 TON AC

1 TR per 100 sq ft of the store for best cooling

One ton of air conditioning can remove 12,000 BTUs of air per hour.

A ton of refrigeration is defined as the rate of heat transfer that results in the melting of 1 short ton (2,000 Pound or 907 kg) of pure ice at 0 C (32 F) in 24 hours. The value is defined as 12,000 BTU per hour, or 3517 watts.

1 TON=12000 BTU=3517 Watts=400 CFM

Here unit Watt* is not the Rated electrical power consumption in watt. But it is the rate at which work is done or energy is transmitted. Watt* = joules/second

Cable Capacity

For Cu Wire Current Capacity (Up to 30 Sq.mm) = 6X Size of Wire in Sq.mm

Ex. For 2.5 Sq.mm = 6×2.5 = 15 Amp, For 1 Sq.mm = 6×1 = 6 Amp, For 1.5 Sq.mm = 6×1.5 = 9 Amp

For Al Cable Current Capacity = 4X Size of Cable in Sq.mm, Ex. For 2.5 Sq.mm = 4×2.5 = 9 Amp.

Nomenclature for cable Rating = Uo/U

where Uo = Phase-Ground Voltage, U = Phase-Phase Voltage, Um = Highest Permissible Upto 25sqmm, these relation works fine. After that, multiplying factor decreases and near 400sqmm, ampacity become almost equal to sqmm for Al and 1.5 times for copper. The current carrying capacity of a cable depends on a number of factors some of which are- Type of conductor used (copper or aluminium) Type of insulation used over the cable( PVC or XLPE, XLPE is more heat resistant) The environmental conditions Length of cable required Copper cable Current Carrying Capacity (XLPE insulated) Cable Size  in (Sq. mm) Single Core Two Core Three/Four Core 1 17 13.5 9 1.5 22 17.5 15.5 2.5 30 24 21 4 40 32 28 6 51 41 36 10 69 57 50 16 91 76 68 25 119 101 89 35 146 125 110 50 175 151 134 70 221 192 171 95 265 231 201 120 305 269 239 150 334 300 261 185 384 341 296 240 459 400 346 300 532 458 394 Aluminium cable Current Carrying Capacity (XLPE insulated) Cable Size  in (Sq. mm) Single Core Two Core Three/Four Core 4 16 13 11 6 20 16 14 10 25 22 19 16 35 31 28 25 43 41 36 35 65 59 52 50 80 71 63 70 91 80 71 95 120 115 100 120 153 133 118 150 188 161 140 185 230 203 176 240 270 254 220 300 340 314 270

Note that in the above current-carrying calculation is done based on the XLPE insulation. In PVC insulation the same capacity will be reduced by 5%. How to calculate aluminium bus bar current carrying Capacity? Aluminium current-carrying is equal to 0.8 times of the total volume of the aluminium (length*breath*thickness). Current carry capacity of 35 sqmm bar= 0.8* 35 = 28 Amps. How to calculate Copper bus bar current carrying Capacity? Copper current-carrying is equal to 1.2 times the total volume of the copper (lenth*breath*thickness). Lets us have a simple example of 35 sqmm bus bar. Apply our equation, Current carry capacity of 35sqmm bar = 1.2* 35 = 42 Amps.  Cable Coding (IS 1554) :( A2XFY / FRLS / FRPVC / FRLA / PILC) A Aluminium 2X XLPE F Flat Armoured W Wire Armoured Y Outer PVC Insulation Sheath W Steel Round Wire WW Steel double round wire Armoured YY Steel double Strip Armoured FR Fire Retardation LS Low Smoke LA Low Acid Gas Emission WA Non Magnetic round wire Armoured FA Non Magnetic Flat wire Armoured FF Double Steel Round Wire Armoured

Current Capacity of Equipment

Three-phase capacitor current = (kVar x 103) / (√3 x V)

1 Phase Motor draws Current = 7Amp per HP.

3 Phase Motor draws Current = 1.25Amp per HP.

Full Load Current of 3 Phase Motor = HPx1.5

Full Load Current of 1 Phase Motor = HPx6

No Load Current of 3 Phase Motor = 30% of FLC

KW Rating of Motor = HPx0.75

Full Load Current of equipment = 1.39xKVA (for 3 Phase 415Volt)

Full Load Current of equipment = 1.74xKw (for 3 Phase 415Volt)

Earthing Resistance

Earthing Resistance for Single Pit = 5Ω, Earthing Grid = 0.5Ω

As per NEC 1985 Earthing Resistance should be < 5Ω.

Creepage Distance = 18 to 22mm/KV (Moderate Polluted Air) or

Creepage Distance = 25 to 33mm/KV (Highly Polluted Air)

Minimum Bending Radius

Minimum Bending Radius for LT Power Cable = 12 x Dia of Cable.

Minimum Bending Radius for HT Power Cable = 20 x Dia of Cable.

Minimum Bending Radius for Control Cable = 10 x Dia of Cable.

Insulation Resistance

Insulation Resistance Value for Rotating Machine = (KV+1) MΩ.

Insulation Resistance Value for Motor (IS 732) = ((20xVoltage (L-L)) / (1000+ (2xKW)).

Insulation Resistance Value for Equipment (<1KV) = Minimum 1 MΩ.

Insulation Resistance Value for Equipment (>1KV) = KV 1 MΩ per 1KV.

Insulation Resistance Value for Panel = 2 x KV rating of the panel.

Min Insulation Resistance Value (Domestic) = 50 MΩ / No of Points. (All Electrical Points with Electrical fitting & Plugs). Should be less than 0.5 MΩ

Min Insulation Resistance Value (Commercial) = 100 MΩ / No of Points. (All Electrical Points without fitting & Plugs).Should be less than 0.5 MΩ.

Test Voltage (A.C) for Meggering = (2X Name Plate Voltage) +1000

Test Voltage (D.C) for Meggering = (2X Name Plate Voltage).

Typically the local utility provides transformers rated up to 500kVA For maximum connected load of 99kW,

Typically the local utility provides transformers rated up to 1250kVA For maximum connected load of 150kW.

The diversity they would apply to apartments is around 60%

Maximum HT (11kV) connected load will be around 4.5MVA per circuit.

4No. earth pits per transformer (2No. for body and 2No. for neutral earthing),

• Voltage Variation(1 to 1.5%)= ((Average Voltage-Min Voltage)x100)/Average Voltage
• Ex: 462V, 463V, 455V, Voltage Variation= ((460-455) x100)/455=1.1%.
• Current Variation(10%)= ((Average Current-Min Current)x100)/Average Current
• Ex:30A,35A,30A, Current Variation=((35-31.7)x100)/31.7=10.4%
• Fault Level at TC Secondary=TC (VA) x100 / Transformer Secondary (V) x Impedance (%)
