The design and construction of items which will be connected to the mains supply where the use of electricity is peripheral or fundamental (eg, low-voltage power supplies for electronics).Instruction in the repair and maintenance of equipment.The construction of electronics circuits from prepared modules or components.

The creation of a joint between the faces of sheet metal components or between wires and terminals using molten solder with a flux. 

This guidance is for choosing batteries for general practical circuit work, where pupils experiment with low-voltage circuits by connecting batteries , torch bulbs, buzzers, small motors and other low-power components to investigate electrical characteristics, parallel and series circuits, etc. 

This guidance is additional to all standard operating procedures across your school and CLEAPSS Guidance in general.

This guide will be regularly updated and should be read in its entirety. Users may also need to read the other guides listed below.
