What are NEIS? National Electrical Installation Standards (NEIS) are the first and only quality and performance standards for electrical construction. They go beyond the minimum safety requirements of the National Electrical Code (NEC) to define what is meant by installing electrical products and systems in a “neat and workmanlike manner.”

    Charlie, a way to avoid the GFCI requirement is to provide a dedicated branch circuit to the appliance and then "hard-wire" it to the circuit by removing the attachment plug cap.

    The fly in the ointment is 110.3(b) for the listed appliance being modified by removal of the plug cap. However, one could take the stance that since this is NOT prohibited by the NEC, that it then can be done.

    The rational to justify this is for the appliance losing it's grounding conductor connection because of a broken prong of the plug cap, or whatever. With a hard-wired circuit, such as a dishwasher, gas furnace, etc., the chances of the ground being lost and a shock hazard resulting is very low.

    Remember that GFCI's fail too. Many, that are not periodically tested, exceed the 1/40th second disconnect time allowing hazardous current to pass for too long a time that could initiate ventricular fibrillation. They're not fool proof and do NOT limit current, just the time the current flows.

    There are devices that will provide an alarm, with remote contacts, that are made by companies such as "Goldline". They fit inside a standard switch box, 3-1/2" deep, and work on Class 2, 24 volt 60Hz or DC power. We used to use these powered by an standard class 2 power transformer, for hard wired refrigeration units in laboratories containing temperature (nonexplosive) perishable chemicals, emulsions, etc. An output contact (SPDT) generally went to the building management system to alert someone during off-hour times. The unit was under $100. It also had an optional expander to provide four monitor (SPST) input points.

    A simple logic type thermostatic switch was used for the sensor, such as one set 45F. Since it was class 2 wiring, there was no hazard of fire or shock. These inputs were also investigated and found suitable for some flammable liquid applications, and could be used in conjunction with Intrinsic Safety barriers for more hazardous situations. (only the inputs, not the logic device). These designs were all documented by engineering drawings and procedures, which were reviewed by qualified technical engineering personnel. They were also reviewed and accepted by the local AHJ.
