Today we were at Sehoale installing a distribution board and connecting the power supply. We drilled the wall first the mounted the db, we used a 20A, 10A and 5A circuit breakers for the lights and plugs. We connected them separately not using a mixed circuit.
We are going to start with a new manual which is maintain and adapt oral communication.

We went to Lethabo Power station somewhere around Vereeneging for a day tour. I saw many fascinating stuff such as boilers, generators and turbines, it was a great experience for all of us. They said that it took about 10years to build a powerstation and they completed the station in 1990. They use coal for the station because its cheap and it was the nearest coal mine they could find.
Coal is used to burn water which changes into steam, the steam turns the turbine blades, the turbine blades turns the generator then the generates electricity.
