What are insulated screwdrivers for if you’re not supposed to work on a live circuit?
The idea is to not rely on any single point of failure. For you to be planted six feet under, you want at least three things to have gone badly wrong at the same time.


Your lockout padlock fell off.
Someone didn't realise you were working on the circuit and switched the breaker back on.
You forgot to turn off the isolator switch.
You didn't notice the puddle of water you were standing in.
You were not using an insulated screwdriver.
Your dog barked at a squirrel and startled you.


Its kinda why you bought a car with seatbelts, airbag and ABS - Does having those items tempt you to jump red-lights in front of large trucks or freight trains?
