Ac wiring symbol. Allowable wire and cable types and sizes are specified according to the circuit operating voltage and electric current capability with further restrictions on the. Alternating current ac is an electric current which periodically reverses direction in contrast to direct current dc which flows only in one direction. Symbols of lines wires cables and electrical conductors. Following is the list of all alternator and generator symbols.
Electrical wiring is an electrical installation of cabling and associated devices such as switches distribution boards sockets and light fittings in a structure. Alternating current is the form in which electric power is delivered to businesses and residences and it is the form of electrical energy that consumers typically use when they plug kitchen appliances televisions fans and electric lamps. Current transformer is a type of instrument transformer used for decreasing high alternating current in a line down to safe levels for measurement purposes. Introduction for air conditioning systems types introduction for types of motorscompressors used in air conditioning systems.
We walk through some of the basics and most common symbols associated with reading an air conditioner wiring schematic or diagram. Electrical rules and calculations for air conditioning systems i explained the following points. The electrical currents are movements of electric charges electrons through a conductor. The current produced in its secondary is proportional to the current in its primary conductor it is measured by connecting it with a conventional ammeter.
Are materials that conduct electricity easily such as certain metals. It is the symbol of a 3 phase ac synchronous generator whose each winding is accessible. His unit is the ampere and is measured by the ammeter. In article electrical rules and calculations for air conditioning systems part one which was the first article in our new course hvac 2.
