The quality of the electricians who fits the sockets is very important. When I had my home cinema room rewired, I told them what I wanted and why. All sockets were specified as premium grade M&K (a UK brand) which have a much better internal switch mechanism (we have individually switched sockets) than the basic cheap ones. The electricians were very careful about terminations and checked each socket individually for good voltage, earth leakage, phase, etc. Anything that wasn't to spec. was re-terminated and remeasured.

They also rewired some light switches, giving extended light bulb life, and replaced two very dodgy cheap sockets in domestic areas (kitchen, office) that were overheating internally and just waiting to cause a disaster. Money well spent.

So my advice: buy quality outlets but prioritise the spend for the best electrician you can find.

In the spirit of Spinaltap, I would like to confirm that I am not involved in the corrupt theft of a global sport.
