control . They are functionally tested , and clinically assembled according to design requirements . This eliminates the need for on-site electrical connections , reduces the number of qualified on-site electricians and other workers needed to carry out the installation work .
The modular wiring system has many indisputable advantages compared with the conventional wiring system , such as :
● Minimum installation time ;
● Minimum site labour required ;
● Factory pre-assembled and pretested ;
● Utilising Plug and Play components ;
● Less containment required by using a cable basket ;
● Quality assurance as the system is manufactured in a factory ;
● Safe installation as the system is colour coded and has polarised connections ;
● Zero wastage as the system is preassembled in a factory ; and
● Cost savings .
Modular Wiring System Components ( I-MOS SYSTEM )
Modular Terminal Box
The TB provides connectivity via a length of Modular Fly Cord lighting or power ( 3-Cores 1.5 or 2.5mm 2 PVC / Copper Wire ) connected to the lighting or the power sub-circuit supply to a Modular Ceiling Distribution Box .
Modular Ceiling Distribution Box
The modular Ceiling Distribution Box ( CDB ) is for the lighting or power distribution sub-circuit connections . It provides two-way connections for the lighting and power sub-circuits using plug and play modular components .
This CDB provides connectivity via a length of Modular Fly Cord lighting or power ( 3-Cores 1.5 or 2.5 mm 2 PVC / Copper Wire ) connected to the Luminaire Box ( LB ) or Power Box ( PB ).
Modular System Switch Box
The Terminal box ( TB ) is placed or mounted next to the incoming cable management trunking or cable basket . It is installed using a metal clamping base plate accessory .
It provides easy electrical installation for the lighting and power sub-circuits . The sub-circuit wiring is installed using trunking or cable basket from the Distribution Board to the TB . This is the first operation on-site by the installer .
This Switch Box ( SB ) is for the sub-circuit light switch connections . It provides switched and unswitched ( by-pass ) connections from the light switch to the CDB and the LB using plug and play modular components .
