Today, I will explain Electrical Wiring for different Air-Conditioning Systems types. This information designed by the electrical designer will be and must appear on the electrical power systems quality pdf drawings for proper installation by the electrical contractor. Understanding how different HVAC equipment operates in a certain HVAC system.

The above points can be fulfilled by understanding the electrical wiring diagram of individual HVAC equipment and of the whole system also. Also the HVAC designer will need to know the size of the electrical loads to assess the impact of the heat generated by the electrical system on the HVAC load. 2- How to get the Electrical Wiring for Air Conditioning systems? It is the most common type of wiring Diagrams. It is called ladder because the symbols that are used to represent the components in the system have been placed on the rungs of a ladder. A typical schematic of a packaged air conditioner is shown in Fig. In electrical schematics, the symbols stand for various components in the circuit, and the lines stand for the wires connecting them.

The intention of the overall schematic is to show how the circuit functions, not how it actually looks. A wiring schematic shows the condition of a piece of equipment when there is no power being applied to the unit. It usually includes drawings that more closely resemble the components themselves, rather than symbols. 5 on the previous page is an example of a typical line diagram.

6 is a typical installation diagram for a residential cooling system. This is called the load side. So when you order be sure to specify marine parts. To enable me access some of the materials on your site.

5 and note the differences in the way that motors, switches, and transformers are represented. Today it is not uncommon for some manufacturers to show both types of diagrams on their equipment. This diagram is used primarily by the installing contractor. It normally shows only what the terminal board connections are, and very rarely will it include any internal wiring of the unit. 6 is a typical installation diagram for a residential cooling system. 4- How to read Electrical Wiring Diagrams? R industry, ranging from 575-V, three-phase power supplies to 24-V control circuit voltages.

Power supplies may be indicated by solid lines or by dashed or dotted lines. Most schematics use straight lines to represent the wires that connect components to each other. This means that one wire simply crosses over the other wire. Not all manufacturers follow the same schematic diagram practices and you will see several different styles of wiring diagrams. If dots are used to show junctions, then intersecting lines without dots mean that the two wires cross without connecting. If loops or jumps are used to depict crossovers, then wires that meet—even without dots—are connected.
