Amprere | the unit of measurement of current (electricity flowing through a conductor) |
Voltage | the electromotive force that causs current to flow through a conductor is called |
Watt | is the unit of measurement of electrical power |
Watt formula | is current x voltage |
Circuit | is a path consisting of two or more conductors carrying electricity from the source to its destination |
Circuit breaker | is a switching device that automatically opens the a circuit when it is overloaded |
Conductor | is a wire or other material used to carry electricity |
Conduit | a channel or pipe in which conductors run |
Convience receptacle | an outlet where current is taken from a circut to sereve electricle devices such as lamps, clocks, and toasters |
Service entrance | equipment including the conductors from the utility pole, the service head |
Disttribution Panel | also called the breaker panel that recieves and distributes it through branch circuits |
Ground | is a wire connectiong the electrical circut or device to the earth to minimize injuries from shock |
Grouns Fault Circuit Interrupter | should be installed where moisture may be present in areas may be present |
National Electrical Code | is a electrical minimum |
Straight or curved lines | indicate which outlets and switches are connected however the actual path is not usually where the line |
Wiring diagram | is used when wiring details cannot be shown clearly on the plan |
Panel Schedule | all of the information associated with a distribution panel is included in |
Lighting Schedule | the permanently mounted light fixtures used in the project can be listed |
Equipment schedule | is similar to a lighting schesule it lists equipment rather than light fixtures |
One line diagrams | are schematic drawings that show pieces of equipment connected electrically |
Circuit | is the path of electricity from a source |
Service entrance | through a meter and on to the distribution panel |
Branch circuits | can be classified by general lighting, general appliance, individual circuits, Dedicated circuits for special equipment |
Circuit calculations | should be made by the engineer are measured iin watts and multipilied |
Low voltage systems | the use of this makes it possible to switch any light or outlet to any possible to switch |
Conductors | are usually copper can be aluminium |
Wire size | as the number decreses the wire size increases reffered as "aught" |
American wire gauge | is the normal way for things to look at stuff |
Conduit | is enclosed tubing used to carry electrical conductors |
Raceways | conduit and other types of enclosed channels used to hold conductors are reffered to as |
American Welding Society | has developed standard procedures for using symbols to indicate the location, size, strength, geometry and details of a weld |
Weld symbol | indicates the specific type of weld |
Welding symbol | consists of the weld symbol and any additional informationneeded to completely specify the required weld |
Refrence line | is the horizontal line portion of a welding symbol it has an arrow |
Arrow | is used to connect the welding symbolrefrence line to one side of the joint to be welded |
Tail | notes are placedwithinto designate the welding specification, process, or other refrence |
Weld dimensions | are drawn on the same side of the refrence line as the weld symbol |
Contour symbol | next to a weld symbol indicates welds that are flat, convex, or concave faced |
weld all around symbol | indicates that the weld extends completly around a joint |
The field weld symbol | consists of a small line and tri angle origaniting at the intersection of the refrence line and arrow |
Melt-through symbol | indicates where 100% joint or member penetration is requied |
Groove weld | may include specifactions for the groove angle depth of preperation |
Groove angle | is shown on the same side of the refrence line as the weld symbol |
Spot welds | are specified by their diameter strength in pounds pitch and numbers |
Labor costs | you must determine the labor rates for each trade such as carpenters, electricians and plumbers |
Production rates | which is established how much material can be installed per hour or day |
Overhead | is the cost of doing buisness for a company |
Approxmate method | is also known as budget parameter estimating |
Budget parameter estimating | is used by owners architects or contractors to determine a rough estimate |
