Energy Management Equipment and Accessories

The products as covered are load management control devices intended to energize or de-energize electrical loads to achieve a desired use of electrical power. In addition, some of the products may have provisions for meter switching to differentiate between “on peak” and “off peak” power usage. Load management control may be accomplished by employing integral or remote accessories such as time clocks, low voltage switching devices, temperature sensors, utility controlled radio receivers, or a combination thereof. In addition, some units may incorporate one or two meter sockets for watt-hour meter installation and switching or may not have any provisions for watt-hour meters.

The primary application, installation of and access to these products is restricted by utility company authorization. Depending upon various utility policies, state and/or local electrical inspection policies and jurisdictions, the final ownership of these products may be (1) utility retained ownership, (2) utility leased or, (3) property owner. Regardless of ownership, in all cases, the electric utility provides a meter seal on the enclosures and they are not to be tampered with, serviced, or modified without utility permission. Since these restrictions preclude any direct access to the products by the ultimate consumer, such things as inaccessible fusing, live fuses, live terminal blocks, etc. have primarily been designed on the basis of electric utility company requirements and may or may not include normal industrial and/or commercial safety standards.

Depending on utility company requirements, the products may or may not be partially or completely factory wired. Some installations may also include additional components such as a radio receiver or a current transformer which is supplied and field installed by the utility company. Proper installation and intended applications of these products must be specified and authorized by the utility company with ultimate liability being the responsibility of the utility.

A product that contains features, characteristics, components, materials, or systems new or different from those covered by the requirements of the standard, and that involve a risk of fire, electric shock, or injury to persons have been evaluated using the appropriate additional component and end-product requirements as determined necessary to maintain the acceptable level of safety as originally anticipated by the intent of the standard. A product whose features, characteristics, components, materials, or systems conflict with specific requirements or provisions of the standard have been judged to be in non-compliance with this standard.
