7.8. BSPS Cabinet Power Requirements
The following section describes the BSPS cabinet mains power requirements.
Warning: The following information assumes a fully populated BSPS cabinet
with main and extension power racks fitted.
Cable sizes and electrical circuit protection devices discussed in the following
section are typical for 230 Volt AC circuits only. Adjustments are required fo
r
other applications.
! Within the BSPS cabinet protected AC mains feeds are required for the main
power rack and two power outlets.
! Both power outlets are to be installed within the cabinet on an independent radial
circuit. Sockets are to be used for the connection of ancillary test/commissioning
equipment only. The type of socket used is dependant on local electrical
requirements.
! Power within the BSPS cabinet is to be distributed from a modular AC consumer
unit fitted with a 100 amp DP isolator. The unit is to be a metal-clad type with
sufficient outputs for services in the cabinet.
! The following tables displays the protective device rating and cable specification
required for each element of the cabinet AC circuit.
