2.5.1 TAG FOR VOLTAGE AND CT CONNECTIONS
Product to be protected by an external fuse, model KTK-1 by
Bussmann, or similar, rated 600V, 1A. It should be provided with a
MCCB or equivalent device to switch off the system from the power
supply circuit. The power supply and voltage measuring circuit is
connected with cable minimum cross section of 1 mm
2
(AWG 17). The
current transformer secondary side connection line should have a
minimum cross section of 2 mm
2
(AWG 14 Cu) and with a minimum
temperature rating of 60 ºC.
