House Wiring and Electronics.
Day 1:
On the first day of work experience, my Dad and I set out drawing and understanding switches. For our electrical board, we needed to install two, two way switches and multiple intermediate switches. We also were looking at a circuit breaker we had.
To understand what these are, here is a simple explanation. A one way switch with only two contacts is used to control a single light. A two way switch (two of them) is used to control a single light from two different positions. Also a two way switch (two of them) plus intermediate switches are used to control a light from many different positions. A two way switch has three terminals, while an intermediate has four contacts. We then proceeded to look at two way switches that we had bought.
Also circuit breaker is usually a six amp, limiting the flow of current to a maximum of six amps. The cable size used to lighting circuits is 1.5 sq mm. Here are some drawings we did to have a better understanding of what we were doing.
