Existing Switchgear Infrastructure ( If applicable )

a)

To what extent does the existing electrical infrastructure determine the possibilities?

b)

Can critical and non-critical circuits be grouped together in busbar banks to facilitate automatic shedding/reinstatement?

c)

Is automatic sequenced shedding/reinstatement of non-essential and secondary maintained loads desirable/feasible in context of existing switchgear?

Supply size,connected load,Generator size

a)

What percentage mains cover will gen-set provide?

b)

How does above relate to existing connected load?

c)

Will anticipated future loads fit into critical category?

d)

Does current rating of c/o device take account of expansion?

Maintainability

a)

b)

c)

If 4 pole changeover contactors employed ( i.e. in 200-630 Amp range ), is maintenance bypass switching required (e.g. for coil-change).

If 4 pole motorised moulded case circuit breakers employed ( i.e. in 600-1200 Amp range), are plug-in withdrawable devices considered necessary?

If 4 pole motorised Air Circuit Breakers employed ( i.e. 800-4000 Amp range ) is a stand-by ACB moving portion/ACB withdrawal lift truck required?
