The difference between a quality tradesman and a trained monkey.
Unfortunately there obviously aren’t enough trained monkeys about, so they have to put up with us quality tradesmen instead.
The last EM lighting installation I installed, they specified metal adaptable boxes to be used as junction boxes.
Unfortunately there was no provision for earthing the adaptable boxes.
Whilst that may be acceptable on the 28V data side, I do not consider it acceptable on the 230V side.
Me telling the trained monkey resulted in shrugged shoulders, but what else do you expect?
On another occasion I was asked by a trained monkey to fix a non-maintained emergency exit light. In a communal car park.
The fault being that the exit light stays on all the time.
The last time I did a Fire alarm install, one of the trained Monkeys tried to drill through the wall of a bank vault.
This resulted in having to cut off the 1m SDS drill bit flush with the wall, patching the wall and after purchasing a new drill bit, the quality tradesman (me) having to drill a new hole.
To be honest the British Standards for both Fire alarms and EM lighting are not what I consider acceptable.
Then again they are probably written by trained monkeys attempting to safeguard jobs for other trained monkeys.
For instance EM lighting test switches which do not switch off the non-EM lighting. How are you then supposed to verify anything?
