Exterior Bank Equipment Questions

[kspop]

Hello, I am a forman at a manufacturing company making the drive up lanes for banks. I am wondering about the installation of the equipment by third party installers and the companies requirements as far as power disconnects.
At this time, company policy is that the installers are responsible for insurring the installation is "per Code". The units in question are 110V AC and have a junction box for connecting the 110. All control voltage is 12 or 24 V DC.
The Question is, Who would be responsible for the installation of a power disconnect, the Installer or the Manufacturer? The units are UL Rated and, per the company, that satisfies their end of it. Thank You for the Information.

Didn't that get answered here:
UL and the NEC

The National Electrical Code will consider your Remote Teller System as a piece of utilization equipment, which is defined in Article 100 of the NEC.

The NEC covers the premises wiring (system) and the coverage ends at the outlet (also Article 100 definitions) that supplies the Remote Teller System, and the wiring from that point on into the Remote Teller is under UL and such other standards as may apply.

The physical construction of the outlet will vary, depending upon what requirements must be met.

I think you answered your own question:

The units are UL Rated and, per the company, that satisfies their end of it.

That would be my answer also. However, if you are asking if your company can be held liable if a disconnect is not installed, a lawyer would have to answer that. (If I can sue McDonalds because a hot pickle on my hamburger burnt my lip, I would guess your company could be sued for not providing a disconnect).

Keep in mind that different locations have different rules and regulations. In some areas, the NEC is not required. So it is possible that in some locations, a disconnect isn't required at all.

In locations where the NEC is enforced, I think it is the engineer's joh to design the project with the disconnect, the electricians job to install the disconnect, and there is usually an inspector who should verify the disconnect is installed.

One final thought, it is common on lots of HVAC equipment for the disconnect to be provided separately by the electrician. This is a commonly accepted practice.

In Washington State a low voltage electrician can't install 120V circuits.
The answer to part of your question is determined by the local rules and laws concerning licensing of electricians and who can do what.

Tom, I believe that is the major set back, as a compeitor is now doing the service on the units. They are making a stink about "no Disconnects" so they can 'follow' the rules to do repairs. I am sure if it was their equipment, there would not be an issue. But before I start anything, I want to have some back-up (information). Thanks.

kspop,

You don't 'have to start ' anything, as the manf. of the equipment, it is not

your responsability to install a service disconnect for the equipment. If it was

UL would not accept your product. the NEC requires disconnects for many

things such as;

Hot water heaters
electric motors
dish washers
air cond. units

the list goes on and on, none of the above normally come equipped with a

disconnect. Hope this helps you.
