I realize the lockout is required unless a switch is nearby the unit to serve as a disco, however, I wonder how needed it really is, especially in a SFD setting. My builders grade DW lasted for 15 years without needing service. Since that would be a dedicated circuit or at most shared with the disposal the chance of someone turning a breaker on while someone was servicing the DW seems remote.

Its for the simple fact that someone COULD turn the breaker back on.

Then what the heck is 422.32 for? A dishwasher is a MOTOR-DRIVEN Appliance, so IMO you MUST use 422.32 for a DE with a motor over 1/8 HP... Am I wrong? IF so... what the hell is 422.32 actually for?

Is it? A fan is a motor driven appliance. The motor drives the fan, the dishwasher motor doesn't drive the dishes. :rolleyes:

Good question go to 430.102(B) excp. allows a breaker to be locked in the open position. 422.32 directs you to part IX of atricle 430.:smile:

If a breaker lock out device is actually installed on the panel, how often do you think it would get used?

I would bet that a breaker lockout/tagout never gets used in a residential location.

And your 100% right. Point is if the repair man had the option then your not in court.

Why would I go to 430 when dealing with an appliance?

Because if your using 422.32 for your motor-driven appliance (dishwasher) you shall comply with Part IX of Article 430. Per section 422.31 (B) you can lock the circuit breaker in the open position and per section 422.32 using article 430 you can lock the circuit breaker in the open position.

No, it's not fished to the box, it's not even in the wall at that point. I don't get the 'it is

also a fixture' , what does that mean ?

When i roughed them in i coiled up about 3 feet of romex. On trim i reach under DW and pull the wire out. To me thats fishing. And this is a whip to the DW . I never got taged over it. Would you like a staple someplace. Easy enough to put a CJ6 on DW

No, I don't want any staple, but if you got the EI on your bad side He might. It was just

a comment about DW's and NEC.
 
I run nm-b into dishwasher on every house I wire, I don't care for those hidden away pigtails the code has allowed for. I put a switch inside the sink cabinet next to the d.w. that will disconnect the dishwasher. A toggle single pole switch that says on or off. Even if the rest of the house gets done in decora, I put a toggle switch in at that location. H.P. rated. Open the cabinet door, sit in front of the dishwasher like you would if you were going to service it, and the switch is in a direct line of sight from your eyes, (I know, thats a technical screw up, the code says direct line of sight from the equipment getting served, but I say its all in your perspective of where you sit.). I have yet to see this cause any problems, my inspectors seem satisfied with it also.

So in your opinion a dishwasher is NOT a motor-driven appliance? Seems to me the motor drives something in the DW to clean the dishes. :roll:

I was trying to point out that there seems to be conflict between 422.31 and 422.32. A dishwasher certainly falls under 422.31, Disconnection of Permanently Connect Appliances. Once you've satisfied 422.31 why would you need to satisfy 422.32?

So what is a motor driven appliance? Is it any appliance that contains a motor or an appliance where the motor performs the only function of that appliance? I don't know, but it seems like article 422 has two different requirements. 422.31 for a permanently install appliance like a dishwasher and 422.32 for something else that would be covered under Article 430.
