 Water Heater Circuit Breaker

The repair guy snaps the breaker off and then he puts his little padlock on it.
A disco for the WH has never been required here, and I wonder if that is local requirement? Somebody in your area got zapped while installing a tank, no doubt.

That makes sense, but I thought the reason disconnects were required for water heaters and condensers was that the electrical panel wasn't always accessible to a repairperson.
Disconnects for water heaters aren't required around here if the heater is "in sight" of the electrical panel--when the breaker clip isn't used, clearly. It is a local requirement.

The NEC has required a line-of-sight disconnect or a lockout at the breaker for a long time. It shouldn't be a new thing.
You can't prevent a breaker from tripping by holding its lever in the "on" position.

Different country, different perceived hazards, sorry for the diversion.

In Bain's first photo, with the lever "down" wouldn't that prevent the breaker from tripping? What is this device actually called anyway?

Yes. I altered my post to say "on."

Something like that would also be required for a hard wired dishwasher.

My understanding is that the point of either is to prevent some jamoke from coming along while someone is working on the appliance and saying "Hey this breaker is off" and flipping it on. If line-of-sight, the person about to be zapped will say "Hey idiot, step away from that disconnect and go find someone else to kill." If lockout, the idiot would have to get (small) bolt cutters to remove the lock to turn the breaker back on, hopefully causing him/her to say "Oh, someone must really want this turned off since they locked it off." Not quite as foolproof as it requires actually placing the lock. Don't know if this is the real reason or urban legend.
