Answer / ahmed alyassi

My friend if we assume the normal.current is 7 amps
Then due to that split ac is considered it is inductive load
The starting current would be x5 or x4 more
So . 7 times 4 =28 amps

But even if your breaker is 25 lets assume
It might not trip. Immediatly cause the delay and the amps didnt increase alot
I would recommend 32 A for 1ton or 1.5ton

Answer / lalitha

1ton=3.5168kW,
I=p/vcos(theta)
I=3.5168/230*.95
=16.09
For power factor of 0.85 current is 17.98
So to even consider initial rush of current 20A breaker is used

Answer / pawan

dear friend 1TR - 1200WAT= 1.2 KILOWATT
AND watt=v*i

I= W/V =1200/240=5 AMP

YOUR ANS IS 5 AMP DEAR

Answer / raghavendran

A 1 ton AC consumes 3.5KW of power.so under running
condition we can estimate the current consumed as
3500/(230*.8 say)

Answer / nikunj

1 TR = 3.51 kw
Now as per formula, P = V x I x COSphi,
I = P / (V x COSphi) for single phase,
I= P / (1.73 x V x COSphi) for three phase, so you can
easily calculate the current rating required.

my 10 hp submersible pump is tripping when connected through ELCB.I have checked the megger value of the coil's with body.It was found to be 0.2mega ohm.that is leakage is there.But when connected to mccb it is not tripping.no leakage current in the motor.Is it safe to connect to mccb? what are the problem's will arise if future?also tell me in ELCB no neutral is connected to motor.than how ELCB was working?
