Difference between 1.5mm and 2.5mm cables.

Difference between 1.5mm and 2.5mm squared cables.

What is the difference between 1.5mm and 2.5mm cables? This is s question that a lot of people ask. The most widely known difference between these cables is their use.

1.5mm cable is mainly used in lighting circuits. While 2.5mm cable is used in socket outlets.

I will discuss the differences between 1.5 and 2.5mm cables through the wire load capacity.

1.5 mm wire load capacity.

What is wire load capacity? This is the current in amperes that a cable can carry safely without being stressed. When you exceed the wire cable capacity, the cable will heat up.

This heat can either melt the insulating material of the cable or the wire itself.

What is the 1.5 mm wire load capacity? The recommended current for a 1.5mm squared cable in a 230v circuit is 10A.

The 2.5mm wire load capacity is 16A-32A. Most in residential home settings, you can use a 16A circuit breaker and a 32 A circuit breaker in-ring circuit. However, there are other factors that can affect the amount of current that a 2.5mm squared can carry.

Factors like the allowed voltage drop, the length of wire run and the type of insulation used.
