What is the cable size required for a 250 amp and 160 amp load?
For a 250 amp load, a cable size of at least 3/0 AWG (American Wire Gauge) or 70mm^2 is recommended. For a 160 amp load, a cable size of at least 1/0 AWG (American Wire Gauge) or 50mm^2 is recommended. It is important to consult local electrical codes and regulations to ensure compliance.
What is the type and size of cable gland or 2 core cable?
To answer this question the size of the cable or the amperage of the load is needed to calculate the correct wire size and connectors to fit the cable.
Size 134 kva cable?
A 134 kVA cable typically refers to the size of cable required for a 134 kilovolt-ampere electrical load. The size of the cable needed will depend on factors such as the length of the cable run, the voltage drop allowed, and the type of insulation and conductor material required to safely carry the current. It is recommended to consult with a qualified electrical engineer or contractor to determine the specific cable size needed for your application.
Could you Calculate cable size for 100 kw load?
To calculate the cable size for a 100 kW load, you would need to consider factors such as the voltage of the system, the type of cable insulation, the ambient temperature, and the installation method. The cable size is typically determined by the maximum current the cable will carry without overheating. Using the formula: Cable size (mm²) = (2 x L x I x R) / (√3 x V x cosΦ), where L is the cable length, I is the load current, R is the resistance of the cable, V is the voltage, and cosΦ is the power factor, you can calculate the appropriate cable size for the 100 kW load.
How do you calculate cable size from the 1500 mm length?
To calculate the cable size for a 1500 mm length, you need to consider factors such as the load current, voltage drop, and the type of insulation material. First, determine the current carrying capacity required based on the load. Then, use a voltage drop formula to ensure the drop is within acceptable limits, typically around 3-5% of the supply voltage. Consult cable sizing charts or standards that provide guidance based on these parameters to select the appropriate cable size.
How do you calculate the requirement of cable size for a given load?
If you know the size of the load to be served, multiply it by 125% ( times 1.25) and choose a conductor that is rated for that ampacity or higher.
For 100kw which cable size is good and how to find out cable size?
100 kw is the power drawn by the load. to calculate the cable size you need to know the voltage. From that you can calculate the current. this decides the cable size. for example if the voltage is 400Volts then the current flowing in the circuit when the load is 100 KW will be 250 amps. (100,000/400). for 250 amps to flow with out causing excessive heating of the cable the cross sectional area of the copper cable should be 150 sq mm.for a round cross section the diameter will be roughly 15mm.
What is the cable size required for a 390 amp load?
The required cable size for a 390 amp load depends on several factors including the type of insulation, temperature rating, length of the run, and whether the installation is in a conduit or exposed. Generally, for copper conductors, a cable size of at least 250 kcmil is often recommended; for aluminum conductors, a larger size may be necessary, typically around 350 kcmil. It's crucial to consult the National Electrical Code (NEC) or a local electrical code for precise calculations and to account for factors like voltage drop and ambient temperature. Always consult with a qualified electrician or engineer for specific applications.
What is cable size in mm2 required for 450 amps?
To determine the cable size in mm2 required for 450 amps, you need to consider the current-carrying capacity of the cable. The exact size will depend on the type of cable and the installation conditions. For 450 amps, heavy-duty cables with a size of around 240 mm2 or larger would typically be used to ensure safe and efficient operation.
