How do you find the right size wire and cable?

Solved Examples of Proper Wire & Cable Size

  1. Total Load = 4.5kW = 4.5 x1000W = 4500W.
  2. 20% additional load = 4500 x (20/100) = 900W.
  3. Total Load = 4500W + 900W = 5400W.
  4. Total Current = I = P/V = 5400W /220V =24.5A.

How many amps will 16mm SWA carry?

The swa cable is 3-core. The house is occupied by an elderly lady who wouldn’t use any equipment with a big load. I was of thinking of using 16mm because the consumer unit is the kitchen and it would be easier to conceal than 25mm and 16mm is able to handle up to 94A.

What size cable do I need for 200 amp service?

Wire Sizes For 200 Amp Service Wiring 200 amp service requires either #2/0 copper wiring or #4/0 aluminum or aluminum clad wiring. Which wire used is determined by the voltage drop and length of the wiring. Many electrical contractors opt to use #4/0 aluminum or copper-clad wire.

What is 250 MCM wire?

For example, one common wire size used in the NEC has a cross-section of 250,000 circular mils, written as 250 kcmil or 250 MCM, which is the first size larger than 0000 AWG used within the NEC. 1000 circular mil equals 0.5067 mm2, so for many purposes, a ratio of 2 MCM ≈ 1 mm2 can be used with negligible (1.3%) error.

What size breaker do I need for 60 hertz?

Range Gas (posted 2010) – 110 -120 volt, 60 hertz, properly grounded branch circuit protected by a 15/20 amp circuit breaker or fuse.

How much load can a 16mm cable take?

How many amps can a 16mm cable take? The current carrying capacity of 16 sq mm copper cable with PVC insulation is 61 amperes for single phase AC or DC. For XLPE insulated 16 sq mm cable current carrying capacity is 81 amperes.

What is cable capacity?

This is a term for the maximum current carrying capacity, in amps, of a particular device. The current carrying capacity is normally associated with electrical cable and is determined as the maximum amount of current a cable can withstand before it heats beyond the maximum operating temperature.
