Signs in Fountains

shall be a sheet copper or aluminum at least 0.50 mm thick. Using of sheet steel for the enclosure shall be at least 0.40 mm thick.

Enclosure

Shall be an integral part of the attachment plug or shall be located in the power-supply cord within 300 mm.

Ground-Fault Circuit Interrupter

The runway contact conductors shall be guarded, and bridge contact conductors shall be located or guarded in a manner that person cannot inadvertently touch energized current carrying parts.

Locating or Guarding Contact Conductors

The extreme limit of displacement of the wire is within less than 40 mm

Contact Wires

Shall have a minimum of 750 mm to access to live parts where the controls are enclosed in cabinets, the door(s) shall either open at least 90 degrees or be removable.

Clearance

A lighting fixture intended for installation in the wall of a pool or fountain in a niche that is sealed against the entry of pool water.

Dry-Niche Luminaire (Lighting Fixture)

A lighting fixture intended for installation in a forming shell mounted in a pool or fountain structure where the fixture will be completely surrounded by water.

Wet-Niche Luminaire (Lighting Fixture)

A complete, environmentally protected unit consisting of solar cells, optics, inverter, and other components, exclusive of tracker, designed to generate ac power when exposed to sunlight.

Alternating-Current Photovoltaic Module

A mechanically integrated assembly of modules or panels with a support structure and foundation, tracker, and other components, as required, to form a direct-current power-producing unit.

Array

A photovoltaic array that has two outputs, each having opposite polarity to a common reference point or center tap.

Bipolar Photovoltaic Array

A diode used to block reverse flow of current into a photovoltaic source circuit.

Blocking Diode

Photovoltaic cells, devices, modules, or modular materials that are integrated into the outer surface/structure of a building and serve as the outer protective surface of that building.

Building Integrated Photovoltaics

Equipment that controls the voltage or de current, or both, used to charge a battery

Charge Controller

Equipment that regulates the charging process of a battery by diverting power from energy storage to DC or AC loads or to an interconnected utility service.

Diversion Charge Controller

A system comprised of multiple power sources.

Hybrid System

A solar photovoltaic system that operates in parallel with or may deliver power to an electrical production and distribution network.

Interactive System

Equipment that is used to change voltage level or waveform, or both, of electrical energy [also known as a power conditioning unit (PCU) or power conversion system (PCS)] is a device that changes de input to an ac output. Inverters may also function as battery chargers that use alternating current from another source and convert it into direct current for charging batteries.

Inverter

A complete, environmentally protected unit consisting of solar cells, optics, and other components, exclusive of tracker, designed to generate de power when exposed to sunlight.

Module

A collection of modules mechanically fastened together, wired, and designed to provide a field-installable unit.

Panel

The basic photovoltaic device that generates electricity when exposed to light

Solar Cell

The total components and subsystems that, in combination, convert solar energy into electrical energy suitable for connection to utilization load.

Solar Photovoltaic System

A solar photovoltaic system that supplies power independently of an electrical production and distribution network.

Stand-Alone System

Roof-mounted de photovoltaic arrays located on dwellings shall be provided with the__________ to reduce fire hazards.
