Method of Wiring
Sub Circuit wiring has been discussed in detail for
1W Light, 2W Light,5A ,13A and 16A Socket outlets etc.
These needs to be wired prior to wiring of the DB unit
so that when the DB is installed, these circuits can be
connected to the DB.
DB Wiring and Installation.
The DB used will either be Surface mount or Flush Mount
[ embedded] type. The enclosure will have entry points
for connecting feeder cable and sub distribution cables
on top and bottom sides. There will be many types of DBs
in market but the example used here will enable the practioner
to handle any type with ease.The DB has a DIN rail for
installing RCCB,and MCBs. It also has two Cu Connector
Bars , one for connecting all Neutral cables of the sub
circuits and the other to connect all Earth earth cables
used in socket outlets and electrical lighting fixtures.
