We have a bank that has the Service Disconnect located outdoors and they are concerned about tampering. The question comes up- Can I install a padlock on the Service Disconnect to prevent unauthorized persons from turning off the power to the bank. I see the words Readily Accessible in Article 230 and need a second opinion.

IMHO, a 'breakaway' padlock has been acceptable here. That is, after a courtesy call to the local Fire Official usually.

The breakaway lock is acceptable on sprinkler main valves. Again, blessed by the FO

Basically....judgement call time.

Little things like padlocks do not slow down the fire department. If they want in something they have the tools to get in. In this case, the point of a fire axe.
I have seen firemen bust the seal off a meter, pick the ring off and pop out the meter from 4 feet away with an axe.
It is really a couple quick flicks of the wrist.
I bet Trumpy can do it wink

They don't stand in front of it!

George,

The definition of readily accessible does not have any prohibition against locks.

As Greg said, padlocks do not slow down the Fire Department. Having the disconnect outside so they don't have to pull the meter is probably safer for them anyway

I would not have a problem with a FUSED disconnect. That would still provide overcurrent protection.

A non-fused disconnect would be a problem.

Power Company has fusing outside of the building boundary here (ie before the metering gear), these fuses are normally pulled in the case of a building fire.
BTW, the PoCo is responsible for the removal of the fuses and are often responded at the same time as the Fire Service (as part of a pre-determined plan).

Having said that, you also have to think of other systems like sprinkler pumps and other fire control equipment.

Locks on the disconnects outside of commercial buildings are the norm around here.
I would say about 1/2 of them have some old rusted up master lock on them.

All the time here as well. All types of occupancies.
Commercial, the land lord/owner never has keys.
Not to worry.
I vote to allow.

BTW: I don't think it is any thing (regardless of the quality of a keyed lock) That a $100 (USA) cordless and 1/4" bit could not defeat in under 90 seconds.Ya know, Hard steel and soft brass for the important stuff! smile

I think that most fire trucks have bolt cutters on them as standard equiptment. That should be able to take care of the problem quicker than trying to break the lock with an axe.

Bolt cutters will go through it like butter.

I had a pair of small Chinese bolt cutters and offered to go cut the lock of of a friends (a very paranoid friend) gate to his undeveloped property some years ago.

As this pair of cheap cutters dispatched the lock with minimal effort the look on my friends face was priceless.

"What good are locks !?!"

"Not much really :)"
