2. Low-voltage network - Wikipedia

   en.wikipedia.org/wiki/Low-voltage_network

   A pole-mounted three-phase distribution transformer. Low-voltage feeders distributing power to households are placed below the transformer. A low-voltage network or secondary network is a part of electric power distribution which carries electric energy from distribution transformers to electricity meters of end customers.

3. Network protector - Wikipedia

   en.wikipedia.org/wiki/Network_protector

   The secondary grid system improves continuity of service for customers, since multiple sources are available to supply the load; a fault with any one supply is automatically isolated by the network protector and does not interrupt service from the other sources. Secondary grids are often used in downtown areas of cities where there are many ...

4. Split-phase electric power - Wikipedia

   en.wikipedia.org/wiki/Split-phase_electric_power

   The line to neutral voltage is half the line-to-line voltage. Lighting and small appliances may be connected between a line wire and the neutral. Higher-power appliances, such as cooking equipment, space heating, water heaters, clothes dryers, air conditioners and electric vehicle charging equipment, are connected to the two line conductors.

5. Electric power distribution - Wikipedia

   en.wikipedia.org/wiki/Electric_power_distribution

   Closer to the customer, a distribution transformer steps the primary distribution power down to a low-voltage secondary circuit, usually 120/240 V in the US for residential customers. The power comes to the customer via a service drop and an electricity meter. The final circuit in an urban system may be less than 15 metres (50 ft) but may be ...

6. HVAC control system - Wikipedia

   en.wikipedia.org/wiki/HVAC_control_system

   HVAC (Heating, Ventilation and Air Conditioning) equipment needs a control system to regulate the operation of a heating and/or air conditioning system. [1] Usually a sensing device is used to compare the actual state (e.g. temperature) with a target state. Then the control system draws a conclusion what action has to be taken (e.g. start the ...

7. Heating system - Wikipedia

   en.wikipedia.org/wiki/Heating_system

   Trends include the integration of smart home technology for better system control through allowing heat schedules, zones, and remote control. The use of renewable energy sources like geothermal heating, solar panels, and biomass. Current trends are toward heating pumps and using renewable energy/low carbon emission energy to power these heaters ...
