- 5. ELECTRICAL SIGNS ELECTRICAL HAZARD indicatesthat electrical hazard is present in the area. VOLTAGE DANGER indicates high voltage in the area and surrounding equipment.
- 6. INTERPRET TECHNICAL DRAWINGSAND PLANS ELECTRICAL WIRING DIAGRAM • Pictorial diagram is a sketch of electrical circuit that shows the external appearance of each component. Sample Pictorial diagram of two bulbs controlled by single pole switch using 9 volt battery source. https://www.google.com/url?sa=i&url=https%3A%2F%2Fwww.cdli. ca%2Fcourses%2Fep%2Fpredesign%2Ft03%2F02knowledge- skills%2Fact-10a.htm&psig=AOvVaw2MN46KXiUXKzqDIDpcEcf- &ust=1628248638428000&source=images&cd=vfe&ved=2ahUKEwi E7O7-4JnyAhVBxGEKHbFMDqkQr4kDegQIARBX
- 7. INTERPRET TECHNICAL DRAWINGSAND PLANS ELECTRICAL WIRING DIAGRAM Schematic diagram is a sketch showing the components of the circuit using standard electrical symbols. It shows the actual number of components and how the wiring is routed but not the actual location.
- 8. TYPES OF CIRCUIT •Series Circuit is a circuit in which lamps are arranged in a chain, so that the current has only one path to take. Current is the same in each load but the voltage varies. • Parallel Circuit is a circuit in which lamps are connected across the wires. Voltage is the same in each load but the current varies

Editor's Notes
- #4 Practically any electrical fixture found in a house has a symbol that coincides to said fixture on an electrical wiring diagram. These are very useful guide for an electrician or electrical contractor, thus, making the wiring easier to install as well
- #5 The following are common electrical symbols used in sketching wiring plan and diagram.
- #7 The flow of current in a conductor or wire can be represented by diagram. There are two types of diagram: pictorial diagram and schematic diagram It is much like a photograph of the circuit and uses simple images of parts.
- #10 It indicates the position of electrical fixtures such as convenience outlets, switches, lightings, door bells, and others to be installed.
