HOMEWORK 1 (15-07-2019)

What I did yesterday at work?
Last week we had a problem with the 42 KW heater, but we were unable to identify  the cause of the problem
We called the contractor and the electricians cheked the electrical system and detect that the main breaker had been damaged.
They proposed installing a provisory breaker while we bought a new breaker, but the provisory equipment had problems when it was switched on.
Again we had to install the previous device.
