Transcript of Wiring (colour coding)
and electrical circuits
By Alex Tyler Colour Coding Red and brown wires represent that
the wire is always hot and active. Black and blue means the wire
is neutral (not active). Yellow and green wires are called earth
wires they go in the earth and protect your
house from getting electrocuted if there
is a thunder storm. A ground wire is grounded to the earth and acts as the backup wire in the event the neutral wire fails. The Data Cable is connected into your computer and looks just like a normal blue wire hanging out of your computer and makes your internet work.
