There are inspectors who not only check when you have made an error and issue heavy fines and loss of licence, but they also check randomly to ensure people keep to the standards.
Jims way of plug
and play is fine. Also to be realistic, a COMPETENT amateur can do some simple, safe, if not legal
. The problem is many incompetent people are literally too incompetent to make a competent decision on their own competence
and make the most basic safety
. I was handed a drill that had the most simple DIY task performed on it. The owner changed the plug
top. The drill "worked fine" at his house and his mates house, but a someone elses house it kept "cutting off the circuit breaker". The circuit breaker it was cutting off was the RCD (I forgot the name of the USA version, but it cuts power when it detects loss of current
to earth to prevent electrocution).
What the guy done was he joined the neutral to the earth pin on the plug so that whenever the drill was used current
flowed in the earth wires of the house rather than the neutral until it reached the switchboard. However the drill worked. This would liven up any pipes/plumbing in the house, and any metal appliance case that is plugged in when the drill is used. His house did not have an RCD so nothing tripped. If any critical earth connection failed someone having a shower/holding a kettle etc could have been killed.
Just because it works does not mean it is safe. So to anyone thinking of doing your own 240v work, how competent are you really? Do you even understand what I was talking about above?
