## How do I calculate cable size needed?

To calculate the Cable Sizing one needs to divide the voltage running through the cable by the target current. For instance, If your wire has a voltage current of 150 Volts and your target is 30 then you divide 150/30. This gives you your target resistance of 5 which is required.

**How do you calculate cable?**

A = √(i2t) / k

- A, is the minimum size of the cable.
- I, is short circuit current.
- t, is the time for short circuit.
- k is short circuit temperature constant.

**How is cable amp rating calculated?**

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

### How is CPC size calculated?

In order to find the correct CPC size using an adiabatic equation you would have to determine the fault current at the end of the 16a ctt. In order to do this you would have to select a cable, say in this case 2.5mm, and, by knowing the length of the run required, find out it’s R1 + R2 by looking up the ohms per meter.

**What is CF in cable calculations?**

The symbol for correction factor for a BS3036 fuse is Cf and it has a value of 0.725. Therefore the cable size is selected based on the size of the device protecting it, having considered the above…

**How many amps can a 1.5 mm cable take?**

1.5mm Twin And Earth Current Carrying Capacity

NOMINAL CROSS SECTIONAL AREA mm2 | REFERENCE METHOD A* (IN CONDUIT IN WALL) Amps | REFERENCE METHOD C* (CLIPPED DIRECT) Amps |
---|---|---|

1.5mm | 1.5mm twin and earth rating 14.5 Amps | 1.5mm twin and earth rating 20 Amps |

#### What is 11KV cable?

11KV Cable Armoured to provide robust mechanical protection (aluminium wire armour on single core, steel wire armour on multicore), these cables are suitable for direct burial in the ground.

**What is HT cable size?**

Number of Cores | 3 |
---|---|

Conductor Material | Aluminum |

Size | 95 Sqmm X 3c HT Cable |

Armoured | Yes |

**How do you convert KV to HP?**

How to Convert kVA to Horsepower

- Step One: Convert to kW. To convert kVA to horsepower, start by finding the result in kilowatts. Multiply kVA by the power factor, then multiply that by the efficiency if available.
- Step Two: Final Conversion. Finally, divide the kilowatts by 0.746 to get the final result in horsepower.

## How do I convert kVA to amps?

Calculation with line to line voltage

- I(A) = 1000 × S(kVA) / (√3 × VL-L(V) )
- amps = 1000 × kVA / (√3 × volts)
- A = 1000 ⋅ kVA / (√3 × V)
- I = 1000 × 3kVA / (√3 × 190V) = 9.116A.

**What is CPC cable?**

Answered by Sarah, Electrical Safety Expert CPC stands for Circuit Protective Conductor, which is basically the earth wire for the circuit and forms part of a system to join together all exposed conductive (metal) parts and connect them to the main earthing terminal.

**What is the CPC size of cables?**

1.5 sqmm cable has 1.0 sqmm CPC. 2.5 sqmm cable has 1.5 sqmm CPC. 4 sqmm cable has 1.5 sqmm CPC. 6 sqmm cable has 2.5 sqmm CPC.
