Working as an electrician is perhaps the most mentally demanding trade there is. In fact, you’d be stretched to find many jobs that require the same levels of mental arithmetic, concentration, ability and endurance.
Say your home needs a mains upgrade. That most likely means running underground cables to your switchboard – most likely around your garage. But, what sort of cable is needed? It depends on your home’s energy consumption, the distance the cable will need to cover, and the load capacity of the cable itself.
But aside from the bigger calculations, there are hundreds of smaller decisions to make every day. From the alignment of numbers and cables in data points to the fiddly earth testing, there’s barely a chance to switch off.
