Electrical Installation Trainer.
The system must consists of a number of modules which are suitable for the study of electrical measurement, electrical installation and for the troubleshooting of electrical installations.
Each module contains real electrical components such as contactors, switches, lamps, push buttons, timers, circuit breakers and relays. These modules can be arranged on the panel frame stand in a variety of configurations to make many different and interesting installations. Connections between the components or between the modules are made by using 4 mm test leads which plug into 4mm color coded heavy-duty binding posts. This will then allow the students to do the wiring quickly and with many variations
The trainer comes complete with laboratory manual which contains many experiments on electrical installation technology. Mobile training frame stands is available to mount the panels. Storage cabinets must be added to provide a convenient place to store the panel modules.
Unit should be upgradeable and have the ability for Inter connectivity between training systems in the teaching laboratory. Manual provided must clearly show the following educational topics of experiments are met;       

Experiment topics coverage:
Residential Switches and Sockets Familiarization

Specifications:
The modules feature real industrial components that easily and securely fit into the training panel frames.
Special powder coated aluminum rails for plexiglass panels, which gives secure and firm fitting modules.
Panels must be quickly arranged to conduct many experiments.
All electrical connections for each component are brought out to 4mm color-coded heavy-duty binding posts. Wiring from the component to the terminals is also color-coded.
Interconnections between the panels and components are made via 4mm stackable test leads.
Stackable test leads allow multiple connections from a single point, which is very useful when taking electrical measurements. Therefore the student is able to relate the circuit theory with the practical aspects of the real component and actual wiring connections.
