UNDERSTANDING CLASSES of ELECTRICAL CONDUCTORS - lets get counting!

If you look at a datasheet for cables and wires you'll often see conductor class mentioned?
The class of conductor determines how flexible the cable is, the diameter and the resistance.

The subtle difference between the different types can have a dramatic effect on the specification of an electrical installation.

00:00 Electrical conductor classes as defined in IEC 60228. (bs en 60228)
01:02 Common cables and their conductor classes.
01:59 Class 1 conductor - solid copper
03:00 Class 2 conductors - min 7 strands
03:35 Class 5 conductor - e.g Tri-rated cable and flex
04:10 How many strands in a 16mm sq class 5 conductor
05:23 Maximum strand diameters to make a conductor and resistance
05:54 Class 6 conductor - very, very flexible!
06:30 How many strands in a 16 mm sq class 6 conductor
07:46 Missing strands in sub-standard cables
08:40 Stranded conductors have a slightly higher resistance
09:10 Conductor diameters
10:07 Flexible conductors on RCBO"s and consumer unit connections.
