Installing Permanently Connected Appliances: A Guide for Utah Residential Appliance Installers

As an aspiring Utah residential appliance installer, it's essential to understand the requirements for installing permanently connected appliances in your customers' homes. In this article, we'll delve into the specific regulations and guidelines you need to follow to ensure a safe and compliant installation.

Permanently Connected Appliances Rated Over 300 Volt-Ampere

According to Section E4101.8 of the Utah Residential Appliance Installation Code, permanently connected appliances rated in excess of 300 volt-amperes require a ranch circuit switch or circuit breaker located within sight of the appliance or devices that can be locked in the open position. This ensures easy access for maintenance and troubleshooting.

Permanently Connected Appliances Rated at 300 Volt-Ampere or Less

For appliances rated at not over 300 volt-amperes or 1/8 horsepower, a ranch-circuit overcurrent device is necessary. The switch or circuit breaker should be located within sight of the appliance or capable of being locked in the open position, as specified in Section E4101.8.

Additional Requirements for Specific Appliances

Some appliances have unique requirements that must be met during installation. For instance, built-in dishwashers require a receptacle to be installed adjacent to their space, while cord-and-plug-connected range hoods need an individual branch circuit. Built-in dishwashers and trash compactors also have specific cord length measurements from the attachment plug to the plane of the rear of the appliance.

Flexible Cords and Attachment Plugs

When installing appliances with flexible cords, it's crucial to ensure they meet safety standards. Listed appliances marked as double-insulated do not require grounding-type attachment plugs. However, most appliances need a grounding-type attachment plug to terminate the flexible cord. Make sure to check the appliance manufacturer's installation instructions for specific guidance on cord suitability.

Accessibility and Physical Protection

Receptacles for cord-and-plug-connected appliances must be accessible and located in a way that avoids physical damage to the flexible cord. The cord itself should be identified as suitable in the appliance manufacturer's installation instructions and only used where listed as compatible with the appliance.

As a Utah residential appliance installer, it's your responsibility to ensure that permanently connected appliances are installed safely and compliantly. By understanding the regulations and guidelines outlined in this article, you'll be well-equipped to tackle any installation job confidently. Remember to always consult the relevant sections of the Utah Residential Appliance Installation Code and appliance manufacturer's instructions for specific requirements.
