Fusing for Input and Output Wiring
The BOSS input and output wires need to be fused as per BOSS specification. The fusing on the
input and output of the BOSS is critical for two reasons –
Overcurrent Protection/Short Circuit Protection
Safe Disconnect during Maintenance
The recommended current rating of the fuses and disconnects is 1.5 times the rated
current of the BOSS per channel.
o
For 20 Amp rated input use 20 x 1.5 = 30 Amp rated fuse and disconnect per
channel.
There are several options available to protect the device.
Alencon recommends using –
Appropriately rated DC disconnects offered by Alencon Systems
Appropriately rated DC disconnects offered by External Supplier
