Dishwasher GFCI protection-disconnect means

[Meltric_South]

Typically I only like to reserve my comments for industrial applications but I think these two comments could apply here as well.

A disconnecting means does not necessarily mean a disconnect switch. Also I'm not familiar with a "listing" for disconnecting means, as was mentioned by the codes and standards guy. There is one for a switch.

Also light indication is not a valid method for verifying zero electrical energy per NFPA70E with the exception of those nifty self testing devices. The way I read it is light can be used to know when power is on, but can't be used to know when power is off, because the light can fail.

Just a couple of more points for discussion as if there aren't enough already.

..Imagine..While they are working on equipment someone opens panel and turns breaker back on. Service tech gets injured or killed. See how that plays out in court.

For those that disagree with this opinion, do you think the standard start/stop buttons used for motor controls meet the disconnecting means requirement?

Courts never recognized disconnects as suitable substitute for OSHA required LOTO, unless disconnect can be locked out and tagged.

Where is the requirement for a disconnect to close without power?

NEC and OSHA are not exactly on same page with this either.

With NEC disconnects that within sight of equipment typically are not required to have a permanently attached locking means.

OSHA you pretty much can have portable locking means for about anything in sight or not.

But it probably not likely you are locking device in discussion here so would need to go back to the breaker and lock it anyway for OSHA compliance.

I like cord & plug mentioned a couple dozen posts ago?

Roger that.

I'll give it up, if there's a requirement for disconnects to close without power, if DC switch position must be seen 50 feet away, or something else I'm missing that disqualifies the blank GFCI.

The ones with 1 or 2 poles and 30 amp edison base fuse holders are likely a lot less cost.

Part of thread topic is GFCI protection also, so maybe we need a two space loadcenter with a GFCI breaker here.

Oh wait we now need AFCI as well, and it would likely need to be the entire circuit, better run a 30 amp feeder in case inspector wants to call the home run part of the branch circuit, then install dual function breaker in your "local disconnect" that is now also the branch circuit device.
