Capacity for cable 70mm (143-212 amp) and may vary depending on installation method used.
The ampacity for copper is 1000A per square inch, in some places is 700A psi.
No. The larger the conductor the lower the resistance and the higher the ampacity.
The amperage rating is dependent upon the insulation rating. A pair of 25mm squared wires touching each other are rated at 131 amps. Three 25mm squared wires touching each other are rated at 110 amps.
If you want to operate the conductors maximum capacity, the conductor needs the heat, that the amperage produces, to be dissipated. This is why in the electrical code book there are two amperage ratings. The first one is for a free air rating which allows for a high ampacity of the wire. The other rating is for three conductors in a conduit which confines the cooling capacity and so the ampacity rating of these wires is lowered. The same procedure is used in cable spacings in ladder tray networks.
do islec have an agreement with NMB
Allowable ampacity for 10-2 copper NM-B is 30 A.http://www.cerrowire.com/default.aspx?id=46

NMB wire is a type of electrical cable commonly used in residential wiring. It consists of two or more insulated wires bundled together with a bare copper ground wire. NMB wire is designed for use in dry locations and is often used for powering outlets, switches, and lighting fixtures in homes.
Yes, you can connect a 14 gauge NMB 2-wire cable to a 14 gauge NMB 3-wire cable using wire connectors like wire nuts or push-in connectors. Make sure to match the wires by color (hot to hot, neutral to neutral, and ground to ground) and ensure a secure connection to maintain safety and compliance with electrical codes.

The rule of thumb is 1mm square=6Amp so 10mm square will,for safety reasons and for a copper conductor, carry 50Amps.
Note me back
Wire ampacity refers to the maximum amount of electrical current that a wire can safely carry without overheating and potentially causing a fire hazard. It is important to match the wire ampacity with the electrical load to ensure safe and efficient operation of the electrical system. The wire size and insulation material are key factors in determining the ampacity of a wire.
