Isolation lock off device
Required to lock off mob isolator. Better designed mcb with locking capability would be better

Not for MCB's
Whilst this seems to be able to get a very sturdy grip onto the switch of an MCB, due to the curve of the MCB this does not sit flush and as such gives enough leverage that it can be pulled off the MCB switch. I haven't marked it down as I don't feel this is designed for MCB's but for circuit breakers with flat switch surfaces. Just be aware when buying, NOT FOR CURVE FACED MCB's
