Question: Would an ice cuber like you see in restaurants that hold ice cubes or make ice cubes count as appliance or not according to NEC 2017 Article 422? If not then would it count as HVAC in compliance with NEC 2017 Article 440? I have plans that show direct wired ice cuber without any disconnecting means in sight but has lockable breaker and that breaker is not within sight.
Okay, let's break down how the NEC 2017 would likely classify an ice cuber and address the disconnect requirements.1. Appliance vs. Not an Appliance (NEC Article 422)
Definition of Appliance (General)
The NEC doesn't have a single, simple definition of "appliance," but generally, it's a utilization equipment, generally other than industrial, that performs a specific function, like cooking, cleaning, cooling, etc.
Restaurant Ice Cuber
A commercial ice cuber would likely be considered an appliance. It's electrically powered utilization equipment designed for a specific purpose (making and/or storing ice) for commercial use.
Therefore, under normal circumstances, a restaurant ice cuber is treated as an appliance.2. HVAC (NEC Article 440)
Article 440 Scope
Article 440 specifically covers air-conditioning and refrigeration equipment that includes hermetic refrigerant motor-compressors.
Ice Cuber and Refrigerant
Most commercial ice cubers do use a refrigeration cycle with a compressor to freeze the water.
Conclusion
Due to the use of hermetic refrigerant motor-compressors, A restaurant ice cuber falls under Article 440
in addition to being considered an appliance under 422.3. Disconnecting Means and Lockable Breaker (NEC 422 and 440)
NEC 422.31 Disconnection of Permanently Connected Appliances A means shall be provided to disconnect each appliance from all ungrounded conductors. If the disconnecting means is not within sight of the appliance, it shall be capable of being locked in the open (off) position.
NEC 440.14 Location Disconnecting means shall be located within sight from and readily accessible from the air conditioning or refrigerating equipment. The disconnecting means shall be permitted to be installed on or within the air-conditioning or refrigerating equipment.
NEC 440.13 Cord-Connected Equipment For cord-and-plug-connected equipment, the attachment plug shall be permitted to serve as the disconnecting means.
The Problem with Your Plan
Your described installation likely violates NEC 2017 because:1.
No Disconnecting Means in Sight
A direct-wired appliance (ice cuber) requires a disconnecting means to be in sight of the appliance,
OR the breaker must be capable of being locked in the open (off) position
AND be readily accessible to the user. A breaker that's not within sight and not readily accessible doesn't meet the code.2.
Breaker as Disconnect
Using a breaker as the disconnecting means is permitted under certain circumstances.
NEC Requirements Recap
The NEC 2017 requires a disconnecting means for all appliances. The disconnecting means must be within sight of the appliance (or refrigeration equipment). If the disconnect is not within sight, it must be capable of being locked in the open (off) position per 422.31 and readily accessible. For ice cubers that are permanently connected, a breaker can serve as the disconnecting means if it meets the lockable and accessibility requirements.
Recommendations for Correcting the Plan
Install a Local Disconnect
The best solution is to install a dedicated disconnect switch (e.g., a fused disconnect switch, or a non-fused disconnect switch if overcurrent protection is provided elsewhere) directly adjacent to the ice cuber.2.
Relocate Breaker (Potentially)
If relocating the breaker is feasible and it can be made readily accessible, make sure it is lockable.3.
Consult with a Qualified Electrician
Absolutely essential. The specific situation at the installation site might have unique circumstances. A licensed electrician familiar with local codes can review the plans and ensure full compliance.
