Energy Code Ace - For hotel and motel guest rooms, install controlled receptacles for at least one-half of the 120-volt receptacles in each guest room.

SECTION 130.5 – ELECTRICAL POWER DISTRIBUTION SYSTEMS

Nonresidential and hotel/motel buildings shall comply with the applicable requirements of Sections 130.5(a) through 130.5(e).

(a) Service electrical metering. Each electrical service or feeder shall have a permanently installed metering system which measures electrical energy use in accordance with TABLE 130.5-A.

Exception 1 to Section 130.5(a): Service or feeder for which the utility company provides a metering system that indicates instantaneous kW demand and kWh for a utility-defined period.

Exception 2 to Section 130.5(a): Electrical power distribution systems subject to California Electrical Code Article 517.

(b) Separation of electrical circuits for electrical energy monitoring. Electrical power distribution systems shall be designed so that measurement devices can monitor the electrical energy usage of load types according to TABLE 130.5-B.

Exception 1 to Section 130.5(b): For each separate load type, up to 10 percent of the connected load may be of any type.

Exception 2 to Section 130.5(b): Electrical power distribution systems subject to California Electrical Code Article 517.

(c) Voltage drop. The maximum combined voltage drop on both installed feeder conductors and branch circuit conductors to the farthest connected load or outlet shall not exceed 5 percent.

Exception to Section 130.5(c): Voltage drop permitted by California Electrical Code Sections 647.4, 695.6 and 695.7.

(d) Circuit controls for 120-volt receptacles and controlled receptacles. In all buildings, both controlled and uncontrolled 120 volt receptacles shall be provided in office areas, lobbies, conference rooms, kitchen areas in office spaces and copy rooms. Additionally, hotel/motel guest rooms shall comply with Section 130.5(d)4. Plug-in strips and other plug-in devices shall not be used to comply with the requirements of Section 130.5(d). Controlled receptacles shall meet the following requirements, as applicable:

1. Install a control capable of automatically shutting OFF the controlled receptacles when the space is typically unoccupied, either at the receptacle or circuit level. When an automatic time switch control is installed it shall incorporate an override control that allows the controlled receptacle to remain ON for no more than 2 hours when an override is initiated and an automatic holiday “shut-OFF” feature that turns OFF all loads for at least 24 hours and then resumes the normally scheduled operation. Countdown timer switches shall not be used to comply with the automatic time switch control requirements; and

2. Install at least one controlled receptacle within 6 feet from each uncontrolled receptacle or install a multiple-receptacle outlet with at least one controlled and one uncontrolled receptacle. Where receptacles are installed in modular furniture in open office areas, at least one controlled receptacle shall be installed at each workstation; and

3. Provide a permanent marking for controlled receptacles or circuits to differentiate them from uncontrolled receptacles or circuits; and

4. For hotel and motel guest rooms, install controlled receptacles for at least one-half of the 120-volt receptacles in each guestroom. Electric circuits serving controlled receptacles in guestrooms shall have captive card key controls, occupant sensing controls, or automatic controls so the power is switched OFF no longer than 20 minutes after the guestroom has been vacated.

Exception 1 to Section 130.5(d): Receptacles that are only for the following purposes:

Receptacles specifically for refrigerators and water dispensers in kitchen area.
Receptacles located a minimum of six feet above the floor that are specifically for clocks.
Receptacles for network copiers, fax machines, A/V and data equipment other than personal computers in copy rooms.
Receptacles on circuits rated more than 20 amperes.
Receptacles connected to an uninterruptible power supply (UPS) that are intended to be in continuous use, 24 hours per day/365 days per year, and are marked to differentiate them from other uncontrolled receptacles or circuits.

Exception 2 to Section 130.5(d): Receptacles in healthcare facilities.

(e) Demand responsive controls and equipment. See Section 110.12 for requirements for demand responsive controls and equipment, including demand responsive controls for controlled receptacles.

Note: Definitions of terms and phrases in Section 130.5 are determined as specified in Section 100.1(b). Terms and phrases not found in Section 100.1(b) shall be defined as specified in Title 24, Part 3, Article 100 of the California Electrical Code.
