BREAKER AND CABLE SIZES FOR ELECTRICAL CIRCUITS.

How to select the correct size breakers and cables for your electrical circuits. This video will introduce you to the steps needed to calculate maximum loads on a circuit; how to use charts to determine the correct circuit breaker for the load, and how to select the right size of cable for the job. Avoid the dangers of installing cables that are too small and give rise to fire risk, avoid over sizing cables and wasting money on excess copper; the right size matters. Use the tables to ensure that the circuit demands are properly balanced and will function safely and correctly. With just one easy to use formula, this video will enable you to plan jobs more efficiently with the confidence that it has been done correctly according to the Wiring Regulations. Once learnt, remembered for life.
