#### Determining The Proper Size Wire To Use Can Be Easy If You Know What Amperage And Wattage A Wire Can Carry Per Wire Gauge.

In a 2.5mm cable. the measurement is 1.5mm. Subtract three from the final value. Walk into a building supply store and head for the electrical department to buy some electrical wire for a project that we have at home.

#### Since The Calculated Value (30 Amp) At 35°C (95°F) Is Less Than That Of Current Carrying Capacity Of (7/1.04) Cable Which Is 31A. Therefore This Size Of Cable (7/1.04) Is Also Suitable With Respect To Temperature.

This gives you the awg of your wire. Current rating for 35°c (95°f) = 31 x 0.97 = 30 amp. The proper circuit size. as indicated by amperage. is determined by several factors. including the planned load on the circuit. the number of outlets or light fixtures. and the length of the circuit.
