Powering Up!

The first task on our heating list is to provide power for the boiler. Since this requires having our trusty electrician onsite, it makes sense to have him do the initial work to rewire the flat at the same time. This will require us to relocate and replace our old breaker box (also known as a distribution panel or a circuit breaker panel) with a new one - not only to meet the current building regulations, but because the old one is super sketchy! The breaker box is where the power comes into the flat and is then distributed to all the various areas - that's why it's a big job to replace and relocate it - there's a ton of cables going to and from it.

The day started by meeting up with our electrician and going shopping. We ended up spending half the day getting all the electrical materials in Park Royal - an industrial area in northwest London with many supply houses. We went from shop to shop ordering the various components and comparing prices because we could not believe how expensive the cabling was - particularly the very heavy lines that were needed to carry power to the breaker box.

Eventually we made it back to flat - while I was rushing to frame the wall where the new breaker box will go, the electricians were removing the sub-floors, disconnecting the old power lines (after shutting off the power!), and running new the cables.

The actual work at the flat went very quickly - we probably spent more time picking up the materials than rewiring the flat. In the end, the final result was a subtle red line that indicated the boiler had power. I had not realized the old wiring & breaker box was in such a poor state, but I now appreciate how much safer the flat has become - the new wiring and breaker box now meet the current building regulations which are very, very tough.  Without seeing firsthand the differences between the old and the new, it would have been hard to truly understand and appreciate.
