Equipment cabinet power connections
Selecting power connection lugs
Table B-10 identifies recommended part numbers for lugs used for power
connections between the Power Supply Rack and the Control and RF
Cabinets. The maximum wire size accepted by the Control and RF Cabinets
is 2/0. The Control and RF Cabinets use screw type compression connectors
and do not require lugs.
Determining power connection wire size
The cable loop length refers to the total length of wire within a given circuit.
For example, the combined length of the -48 Vdc (hot) lead and the DC
return lead equals the cable loop length. This means that a cabinet which
needs 16 feet of wire between the Power Supply Rack and equipment
cabinets has a total loop length of 32 feet.
The wire size for the connection between the Power Supply Rack and the
equipment cabinets is determined by the required wire length and the
maximum allowable voltage drop. The voltage drop in the loop must be kept
to below 500 mV. The wire selected should be UL-approved and contain a
high number of strands for flexibility. Table B-11 shows the recommended
wire sizes for various loop lengths of the RF Cabinet. Table B-12 shows the
recommended wire sizes for loop lengths of the Control Cabinet
