I have two portable refrigerated units for a local fast food restaurant and they need disconnects and I?m not sure about them being ?readily accessible? or ?accessible?. I say they are ?readily accessible? and they can not be installing these on the roof of these units or does 440.14 apply.

It seems to me that they need only be accessible, not readily accessible. That means they can be on the roof of the unit.

I would say that if they are portable, that there's no reason that they couldn't be cord and plug connected.

It seems to me that they should be on the roof, with the equipment they disconnect.

I would put the disconnect wherever the equipment is.

insparks I missed the walkin freezer part. They are portable walkin freezers? Are these units on trailers?

Does that mean they will become permanent or are they there for a temporary purpose? On concrete pads and attached to building sounds like a perrmanent installation.

Doesn't really matter as they don't meet the definition of portable any ways.

Wouldn't that depend on whether or not they remain on trailer, and if trailer is actually part of the unit. If it is designed to be moved it is portable.

550.2 and 551.2, which is where Portable Appliances sends you, says; An appliance that is actually moved or can easily be moved from one place to another in normal use. It then gives you a list of appliances that are considered portable.
I don't believe that a walk in freezer is portable, even if it's on a trailer. I've moved houses on a trailer, but that doesn't make them portable.

Those sections only apply to mobile homes, manufactured homes and RV's.
What is sending you there?
400.7(A)(3) would allow the use of flexible cord. The next step is to determine if indeed it is portable. If it still has wheels under it or at least a place to easily attach wheels, after installed it is a little hard to say it is not portable.
As far as moving a house on a trailer, if you for some reason wanted to supply power while still on the trailer it is at that time portable and why couldn't you use a flexible cord?

I thought so too, but go to the index and look up Portable Appliances and it says see Appliances. Go to Appliances and it says Portable definition 550.2, 551.2. It also lists Stationary as 550.2, 551.2.
