Whether capacitor loads can be connected for testing a
diesel engine at its full load capacity? Is there any
limitation of capacotir load? Which is the best load for
testing DG sets?

Capacitor is not suitable load for Engine testing, It will
trip high Voltage of AVR if it is sycronous generator.
Best loag for testing resistive.

Answer 1 is correct.
Normally a resistive load is used for testing a DG. As most
DG's are rated at 0.8 lagging power factor the resistive
load is calculated at unity power factor load on the DG.
This is usually 80% of the kva rating. This tests the
engine to full load.
Where it is required to test the generator at full load
also an induction load is used together with the resistive
load to give the correct power factor.
Capacitor loads are not normally used as DG's do not
operate safely on leading power factors.

I just purchased a 4 position cam switch to be used to operate a 3-speed blower motor. The motor is a 10 amp motor and has 3 wires that are used to control speed. The cam switch was rated at 660V 20 amps but when I received it, I noticed that it has AC-15 operational current rating (Ie) of 4/5 amps. If I am reading the label correctly. the 4/5 amps is related to 440v/220V (Ue). Other ratings are AC-3: 5.5A, AC2: 7.5A and AC-4: 1.5A. My questions are 1) Is it safe to use this switch with the motor I have 2) what is the difference between the 20 amp Ith ratting and the Ie operational ratings?
my motor rating is 800HP, 128Amps, 3.3kV. What is capaitor bank i can use for PF improvement to 0.990?
