What is the current carrying capacity of 35 sq mm copper cable?
Current carry capacity of 35 sqmm bar= 0.8* 35 = 28 Amps.
What size wire do I need for a 200 foot run?
Generally speaking, you will need 1 AWG copper or 2/0 aluminum conductors for this to work. This should be large enough wiring to safely carry those 100 amperes. It will also maintain the power quality over larger distances.
How much load can a 6mm copper wire handle?
The regulations allow for a 145% increase in current carrying capacity for one hour so using a 6mm for a maximmum load od 32A with a 32A MCB is acceptable. It is not possible to protect a 6mm cable with a maximum load of over 50A with a 32A MCB.
How the length of wire affect the resistance?
The resistance of a long wire is greater than the resistance of a short wire because electrons collide with more ions as they pass through. The relationship between resistance and wire length is proportional .
How to calculate the size of a copper cable?
Wire Circular mils = √3 x 2 x ρ x I x L / (% Allowable Voltage drop of source voltage ) Note: the Value of ρ = Specific resistance or resistivity of Conductor is used here for copper and aluminum is 11.2 and 17.4 respectively at 53° C (127° F) Also check the “Good to know” Section after the calculator.
