MR249E Educational House For Electrical Installations And Testing Didactic Education Equipment For School Lab Electric Trainer Kit
The educational house for electrical installations has been designed to apply the assembling and testing techniques of electrical installations in buildings of residential, business and service sectors. This system is used to apply the installation techniques according to standards, and in particular, to the safety of electrical installations as explained in the regulations in force. This equipment emphasizes the aspects concerning electrical testing including “visual examination” without any need of “instrumental tests” for checking the installation effi ciency.
EDUCATIONAL HOUSE FOR ELECTRICAL INSTALLATIONS AND TESTING
This equipment represents a small size building for residential use designed to analyze the correct assembling and testing procedures of electrical installations (“Rules for safety of electrical installations”). it is suitable to measure insulation, fault loop impedance and voltage drops, and to carry out continuity tests and checks of protection devices on already wired and operating circuits, besides enabling to carry out changes and transformations on already existing installations.
