3.1.3General Notes

The following are guidelines only and superseded by local regulations and codes of practice where applicable:

1.The neutral conductor should be sized same as the output/ bypass current.

2.The earth conductor should be sized for carrying fault current for atleast 3 to 5 seconds or as guided by local electrical rules.

3.Consideration should be given to the use of paralleled smaller cables for heavy currents, as this can ease installation considerably.

4.When sizing battery cables, a maximum volt drop of 3V d.c. is permissible at the current ratings given in Table 3-1.

3.1.4Cable Connections

The rectifier input, bypass, output and battery power cables (all require lug type terminations) and are connected to busbars situated below the power isolator switches - as shown in figure 3.1 for 80kVA and fig 3.2 for 120 /160/ 200kVA.

A terminal block X3 is used for connecting the control cables to the battery circuit breaker and a second terminal block X4 is used for the external emergency stop facility, external OFF inverter, ext. Bypass, etc. these are female spade type connections (Fast-on 6.3 x 0.8) and are described later in Section 3.2

3.1.5Safety earth

The safety earth busbar is located between the Bypass and Output power supply connections as shown in the figure 3.1. The safety earth cable must be connected to the earth busbar and bonded to each cabinet in the system.

All cabinets and cable trunking should be earthed in accordance with local regulations.
