As with any skill the more experience you have, the more options are open to you in terms of approaching a problem.
I am mostly working on domestic projects and get to see a wide range of new products coming to the market. I also get to see where things have gone wrong for customers and can help people avoid making the same mistakes. A big part of the job is making recommendations about which fittings will work best and to give customers an idea of what’s possible.
Although often considered to be not part an electrician’s area, I recently was asked to add some data cables and some plastering. I gave it a go and was pleased with the result. The customer now has a physical high speed connection in all rooms.
