Mains fed electrical equipment construction - has earth free mains circuit module with two insulating shells to reduce space whilst preserving accessibility

摘要

The electrical equipment includes a front panel, a mains transformer and an unearthed connection between the mains plug and the mains transformer's primary winding. - The configuration is made compact without sacrificing accessibility by constructing the mains circuit within the equipment as an independent, encased, insulated module. This module is located in a recess in the front panel. The module's casing comprises two insulating 'shells' (2) flanged together along one side.
