Lift power supply disconnection time

Apostolos over 5 years ago

Good morning.

Would you classify the power supply from the main distribution panel to the lift as a sub main (5 sec disconnection time) or as a final circuit (0.4 sec disconnection time)?

The lift will take this power supply and ......if I am not wrong ..... distribute it further to lights and other automation components, so doesn't this mean that this is not a final circuit?

Thanks

Might be worth you checking that - 4.0mm2 is a fairly slender cable for a 100m run coupled with a start current already exceeding the MCCB nominal setting in terms of voltage drop

If it really is acceleration current, it may be sustained for a reasonable time step - which is certainly going to start warming up the thermal part of the MCCB
