| Terminology for wiring/ from
waterhetertimer Load = light bulb, motor, fan, heater, pump etc; Total load = add up wattage on all Loads. Resistive Load: incandescent light bulb, heating element have uniform voltage and amp draw; Inductive load: motor, pump etc. Inductive loads pull more amps during start up. Load rating... light bulb shows wattage, label on water heater shows volts-watts, timer labels show rating for inductive or resistive etc Figure volts amps watts Volts x amps = watts Water heater formulas .pdf Hot wire = wire or wires that carry voltage potential and would shock you if breaker was on Image residential breaker box Neutral wire = Grounded Conductor = A system or circuit conductor that is intentionally grounded. By code, a white wire used for 120V and 277V circuits to complete circuit along with a Hot wire. Ground = NEC (national electric code) defines ground: A conducting connection, whether intentional or accidental, between an electrical circuit or equipment and the earth or to some conducting body that serves in place of the earth. Grounded = Effectively. Intentionally connected to earth through a ground connection or connections of sufficiently low impedance (resistance) and having sufficient current-carrying capacity to prevent the buildup of voltages that may result in undue hazards to connected equipment or to persons. Ground wire = green or bare copper wire that connects to ground busbar in breaker box Why ground is needed Grounding electrode = earthing electrode (ground rod) Ground resistance = resistance due to the resistivity of the soil in the vicinity of the grounding electrode 208 and 240 volt single-phase circuits have 2 Hot wires. (US electric) Image residential breaker box Some countries have 230-240Volt circuits with 1 Hot and 1 Neutral (instead of 2 Hot wires). What is 208 volt 120 and 277 volt circuits have 1 Hot and 1 Neutral / Usually 277volt is found in commercial applications (US) What is 277 volt Standard voltages in US and Americas include 12V 24V 120V 208V 240V 277V 480V 600V etc found in various applications Voltages around the world vary depending on country. Standard voltages make it possible to mass produce wires, breakers, appliances etc. 60Hz or 60 cycle = number of times AC generator rotates each second. Americas use 60 Hz power, while other countries use 50Hz. Read more DC direct current is generated by solar panels and batteries. Large arc when switching high voltage DC is fire hazard. Device must show DC rating. Read about DC vrs AC AC alternating current produced by power plant, windmill, or portable generator. More Single-phase = residential electrical systems are single phase AC, requiring 2 wires to complete circuit More Three-phase = commercial wiring requiring 3 Hot wires to complete circuit More Wire gauge = diameter of wire. The wire size and load rating and breaker must match Select wire and breaker Breaker: circuit breaker is overcurrent protection that will trip when amp draw from Load or short circuit overheats wire. Turn breaker fully off and then fully on. Jumper = short wire used to connect 2 electrical points together. Fuse: A piece of metal, connected in the circuit, that melts and interrupts the circuit when excess current flows. Transformer = converts voltage and amperage ratio on a line. Cell phone charger, doorbell transformer, LED driver are examples of changing 120 volt into safe, low voltage applications. On the grid, transformers are used to supply 120-240 to household, and other voltage combinations to local business and industry. Insulation = Common usage: electric wires are coated with insulation to isolate each wire from coming into contact with other wires. Removing the insulation is necessary when connecting wires. Professional usage: The action of isolating sources of electricity from coming into contact with other wires, boxes, earth, people, appliances, etc is referred to as insulation. A fault, where electricity has reached earth unexpectedly or breeched a layer of containment, is known as an insulation failure. In motors: motor insulation is classified by maximum allowable operating temperature. |
