ANR Building, Davis. Staff Meeting. February, 2015. Electrical Hazards/Injuries. Electrical equipment used in office areas is potentially hazardous . and can cause:. Shock. – most common hazard, occurs when the human body becomes part of the path through which the current flows. AT-7000 Advanced Wire Tracer. Updating the Amprobe Wire Tracer Line. AT-4000-A Series. AT-2000-A Series. Product Overview. Functionality:. Traces energized and de-energized wires. Locates breakers. Pinpoints shorts and open wires. Electrical circuits require protection to prevent fire or electrocution in the event of a fault. There are two main types of circuit protection used RCD’s and MCB’s. . (RCD) Residual Current Device.

RELAY. and Ohm’s Law. The basics of electrical measurement. . Voltage is electrical pressure, which is potential force or the difference in electrical charge between two points. Voltage pushes electrical currents though a wire but not through its insulation.. Making Electricity Useful. Circuit Diagrams. Electrical circuits can be shown in diagrams using symbols:. 9.0V. Circuit Diagram Symbols. :. AC. DC. battery. AC power supply. DC power supply. bulb. resistor. Up to this point we have learned that static electricity can build up to a point where it results in the discharge of that energy in the form of a spark or lightning strike.. Next we will draw on your prior knowledge (gr. 6) to help learn about currents and circuits. . Electrical Safety Statistics. On average, there are 70 electrocution fatalities due to consumer products each year. . http://www.cpsc.gov/en/Research--Statistics/Electrocutions1/Electrocutions/.
