Breaker lockout for cook tops and built in ovens.

Section 422.31 requires a disconnect for fixed appliances and 422.33(B) allows a cord and plug for sit in ranges if the drawer is removable.

Are breaker lockouts required when there is a cook top and built-in oven being installed?

If they are required how many are installing them?
 
Doesn't 422.34 provide some relief (unit switches with OFF marking). The difficulty is knowing whether these switches disconnect all ungrounded conductors. I guess you need to post the schematic at the time of inspection.
 
If the clock is lit, the power is on. lockout required. keypads alwas have power on them. I require them and nobody complains.
 
We put lockouts on the breakers to all the built in ovens we do, simply because as Cavie stated, it is still live when even in the off positions.

We also do the same thing if the Water Heater is not in the same room as the service panel.( 422.31(B) )

On our dishwashers and so on we simply do a cord and plug under the sink and allow for the pass thru of the cord.(422.16(B)(2)(2) )
 
Our inspectors have been requiring them for awhile now, water heaters not in site of the panel too.In addition they will let us use them for an a/c unit where the disconnect working space has been encroached when the a/c guys set the unit under the disconnect.
 
Very few inspectors require them in our area. I think it is purposefully overlooked sometimes.

on all dishwashers???
 
They haven't been enforced ever in my town. Some put them in, most don't. Now, for me to buck the status quo, think of it as turning a barge. It just doesn't happen fast.
 
We require breaker lock-out devices on any hard-wired appliance not within sight of the branch circuit overcurrent device that also has no local disconnecting means or unit switch.

How are these lock-out devices to be installed? Are they the lock-out tg-out type or are you requiring them to be permanently installed?
 
Cpal, I just read the link thanks for doing the digging, I was wondering if a dishwasher constitutes a "422.32 motor driven appliance" vs. 422.31 Disconnection of permanently connected appliance (A) & (B) The requirements for the disconnect vary greatly . I'm not sure if a dishwasher is motor driven? or rather an appliance that employs a motor.
 
The locks Bryan is talking about in permenant. It fits over the breaker under the panel cover. Each brand is different. I don't know of a universal lockout. It has a loop to install a lock when the breaker is turned off. The set screw type are not to code. That type is used to keep somebody from accidently turning off a computer, telephone, of emergency circuit.
