DRd Enclosure Installation Manual
Step 5:
Terminate the Neutral as described in the following section, dependant on your
DRd enclosure model.
Non Neutral Disconnect
For enclosures which have neutral jumpers fitted, the Neutral of the load, fed by the
Emergency module, must be connected to the Neutral terminal of an adjacent module.
Neutral Disconnect
In enclosures without neutral jumpers (Neutral Disconnect enclosures), the Neutral of the
load should not be connected to another load’s Neutral terminal. This can cause unwanted
tripping of RCD modules.
Instead, an auxiliary neutral terminal must be fitted to the neutral plate and the loads should
be connected to the terminal. If your enclosure was ordered with Emergency modules from
the factory, the auxiliary neutral terminal will be factory fitted. If you require an auxiliary
neutral terminal for field installation, please contact ETC as shown using the details in
.
