Technical Information used in electrical work

A diagram that gives a theoretical picture of a circuit and how it works is a

• Wiring diagram

• Block diagram

• Schematic diagram

• Layout diagram

A layout diagram is not useful for

• Identifying the position of components

• Understanding how a circuit works

• Identifying the route of cables

• The position of accessories and Equipment

When assembling or fault finding on the circuit board in the figure below it is important to be able to quickly find the position of the component. The components are located using a component

• British Standard Euro-Natural

In order to determine types of materials and quantities required to complete an electrical installation, an estimator will require:

• Exploded view diagrams & data sheets

• Operating sheets & manufacturers models

• Specification & wiring diagram

• A technical drawing & data sheet

Diagrams that are designed to give a basic view of the way something works are called

• Wiring diagrams

• Block diagrams

• Circuit diagrams

• Schematic diagrams

When a variation order has been provided it is necessary to produce a

• Night work sheet

• Specification

• Schedule

• Day work sheet

The purpose of the day work sheet is to record

• Hours worked in addition to the main contract

• All worked hours

• All work to be carried out in one day

• Any work related expenses to be claimed from petty cash
