What does mean by 7 29 wire?
7/. 029 is the wire that is used as main wires of each room separately where 7 indicates number of copper conductors inside the insulation and . 029 indicates diameter in inches of each conductor.
How is wire size determined?
Wire gauge sizes are represented through numerical values, AWG 4/0 through AWG 40. The lower the number assigned to a wire the larger its diameter; the higher the number the smaller its diameter. AWG is the numerical standard that established wire gauge sizes for measuring wire gauges in the United States.
How many mm is 7 29 wire?
2.5 mm
7/. 029 (2.5 mm) is commonly used in house, offices and building for room wiring.
What mean by 7 36 wire?
A wire is a single rod of metal with a small ratio of diameter to length. These wires are usually twisted together. For example, cables may be referred to as 7/36. This means it is constructed from 7 strands of 36 gauge wire. (And from the Stranded Wire chart below, we can see that a 7/36 wire is 28 AWG.
What is the best cable in Pakistan?
Green Cables is Pakistan’s leading and trusted export quality electrical cable manufacturer with a range of 99.9\% pure copper cable products.
What is the relationship between wire diameter and AWG size?
American wire gauges (AWG) are a standard set of sizes for wire conductors — the smaller the wire gauge, the larger the diameter in inches or millimeters, and vice versa.
What size is 70mm2 cable?

How many mm is 7 36 wire?
4 sqmm (7/36) is commonly used in house, offices and building for Air condition or load upto 28 amperes.
How do you convert AWG to SWG?
Drawings, technical documents and specifications often describe the wire size in American Wire Gauge (AWG) or Standard Wire Gauge (SWG)….AWG / SWG to millimetre (mm) wire size conversion.
| AWG to millimetre conversion: | ||
|---|---|---|
| Wire Diameter in AWG excluding insulation (AWG 1 – AWG 56) | ||
| Equivalent wire size: | Ø mm | Ø inches |
| Cross sectional area: | mm^2 | inches^2 |
What is the meaning of 3/29 wire size?
This is a method of specifying sizes of stranded wire — (number of strands / gauge of individual wire). 3/ 29 means 3 stands of 29 swg wire (swg— standard wire gauge). Nowadays another practice of specification is also in vogue— ( number of strands/ diameter of individual wire)— 36/.2 means 36 strands of 0.2 mm wire.
What is the difference between 3/29 and 3/029?
So 3/029 is 3 strands twisted together of 0.029 inches copper wire. This is a method of specifying sizes of stranded wire — (number of strands / gauge of individual wire). 3/ 29 means 3 stands of 29 swg wire (swg— standard wire gauge).
What is the cross sectional area of an N-gauge wire?
The n gauge wire’s cross sercional area A n in square inches (in 2) is equal to pi divided by 4 times the square wire diameter d in inches (in): An (in2) = (π/4)× dn2 = 0.000019635 in 2 × 92 (36-n)/19.5 The n gauge wire’s cross sercional area A n in square millimeters (mm 2)…
What color is a 14/3 wire?
The electrician used a 14/3 cable (red-black-white) for each of these new runs, informing me that 1A = Red / 1B = Black and 2A = Red / 2B = Black. I think he did this as a favor to me as I told him I wanted to get my basement fridge on its own circuit.
