Guardian 22,000-Watt (LP)/19,500-Watt (NG) Air-Cooled Whole House Generator with Wi-Fi and 200-AmpTransfer Switch

Nineteen or 19 may refer to:

• 19 (number)
• One of the years 19 BC, AD 19, 1919, 2019

Year 200 (CC) was a leap year starting on Tuesday of the Julian calendar. At the time, it was known as the Year of the Consulship of Severus and Victorinus (or, less frequently, year 953 Ab urbe condita). The denomination 200 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

Generator may refer to:

• Signal generator, electronic devices that generate repeating or non-repeating electronic signals
• Electric generator, a device that converts mechanical energy to electrical energy.
• Tidal stream generator, a machine that extracts energy from moving masses of water
• Generator (circuit theory), an element in an abstract circuit providing a source of electricity
• Engine-generator, an electric generator with its own engine
• Wearable generator, a hypothetical generator that can be worn on the human body
• Gas generator a device, often similar to a solid rocket or a liquid rocket that burns to produce large volumes of relatively cool gas
• Motor–generator, a device for converting electrical power to another form
• Atmospheric water generator, a device capable of extracting water from air

Guardian usually refers to:

• Legal guardian, a person with the authority and duty to care for the interests of another
• The Guardian, a British daily newspaper

A house is a single-unit residential building. It may range in complexity from a rudimentary hut to a complex structure of wood, masonry, concrete or other material, outfitted with plumbing, electrical, and heating, ventilation, and air conditioning systems. Houses use a range of different roofing systems to keep precipitation such as rain from getting into the dwelling space. Houses generally have doors or locks to secure the dwelling space and protect its inhabitants and contents from burglars or other trespassers. Most conventional modern houses in Western cultures will contain one or more bedrooms and bathrooms, a kitchen or cooking area, and a living room. A house may have a separate dining room, or the eating area may be integrated into the kitchen or another room. Some large houses in North America have a recreation room. In traditional agriculture-oriented societies, domestic animals such as chickens or larger livestock (like cattle) may share part of the house with humans.

The social unit that lives in a house is known as a household. Most commonly, a household is a family unit of some kind, although households may also have other social groups, such as roommates or, in a rooming house, unconnected individuals, that typically use a house as their home. Some houses only have a dwelling space for one family or similar-sized group; larger houses called townhouses or row houses may contain numerous family dwellings in the same structure. A house may be accompanied by outbuildings, such as a garage for vehicles or a shed for gardening equipment and tools. A house may have a backyard, a front yard or both, which serve as additional areas where inhabitants can relax, eat, or exercise.

In electrical engineering, a switch is an electrical component that can disconnect or connect the conducting path in an electrical circuit, interrupting the electric current or diverting it from one conductor to another. The most common type of switch is an electromechanical device consisting of one or more sets of movable electrical contacts connected to external circuits. When a pair of contacts is touching current can pass between them, while when the contacts are separated no current can flow.

Switches are made in many different configurations; they may have multiple sets of contacts controlled by the same knob or actuator, and the contacts may operate simultaneously, sequentially, or alternately. A switch may be operated manually, for example, a light switch or a keyboard button, or may function as a sensing element to sense the position of a machine part, liquid level, pressure, or temperature, such as a thermostat. Many specialized forms exist, such as the toggle switch, rotary switch, mercury switch, push-button switch, reversing switch, relay, and circuit breaker. A common use is control of lighting, where multiple switches may be wired into one circuit to allow convenient control of light fixtures. Switches in high-powered circuits must have special construction to prevent destructive arcing when they are opened.

The watt (symbol: W) is the unit of power or radiant flux in the International System of Units (SI), equal to 1 joule per second or 1 kg⋅m²⋅s⁻³. It is used to quantify the rate of energy transfer. The watt is named in honor of James Watt (1736–1819), an 18th-century Scottish inventor, mechanical engineer, and chemist who improved the Newcomen engine with his own steam engine in 1776. Watt's invention was fundamental for the Industrial Revolution.
