I remember a site visit from my NVQ assessor.
id installed a plant room full of pumps, panels ect. The bloke turned up and was impressed. I explained how the system worked (water feature display and filter pump system) and he then asked me to carry out some dead tests.
I linked L-E on one of the pumps, and couldn't get a reading at the terminals in the panel! I started flapping, checking tightness of terminals ect, when he said to me 'you've proved the isolator is doing its job'.
id only left the isolator off!
ive done lots if other stupid things too.
i once fabricated a very tricky set of bends& setsin 300mm heavy duty tray.
there was no room to use manufactured ones, and the measurements had to be perfect.
i fabbed it up, painted it, and it looked brilliant. I was pleased, and the older fellas were saying what a good job I'd done.
when I took it upto the top of the boiler stack to install it, I'd got one of the bends the wrong way around!!!!
i cut the tray at that point, refabbed a new flat bend & external 90degree bend the right way around and altered some joiners to bolt the two bits together!
It looked good, but took nearly twice as long as it should!!
