A 40A MCB is a circuit breaker. The surge current limit is protected to 250A 8/s0uS. The limitation capability of a circuit breaker is that characteristic whereby a current less then the prospective fault current is allowed to flow under short circuit conditions.

What is better gfi outlet or surge protector?

No relationship exists between a GFCI and a surge protector. GFCI protects a human. Surge protector protects a transistor. Most transistorized appliances already contain some robust surge protection. A protector is often unnecessary except for rare events that might occur maybe once every seven years. GFCI is essential to protecting humans especially in locations that have water such as bathrooms and kitchen. GFCI is so important in some locations as to be required by safety codes for over 40 years.

How many kwh will a 40 kw 120v 333a generator produce in 24 hours?

If the generator is rated 40 KW, it doesn't mean the generator pours out 40 KWwhenever it's running. It means you can take as much power as you want from itas long as you don't try and take more than 40 KW for too long, because that couldoverheat or damage the generator.Notice that your 40 KW is just the product of the rated voltage and current:120 V times 333 A = 39,960 watts = nominal "40 KW".We point that out in order to mention that the voltage and current rating of thegenerator are irrelevant to the answer.If you load the generator to its max of 40 KW continuously for 24 hours, thenit delivers (40 x 24) = 960 KWH of energy.

Is it possible that single pole MCB will have 40 amps and 63 Amps rating?

It its rating is 63 amps that means the current can be anything from 0 to 63 amps but not more.


ELCB vs MCB?

Earth Leakage Circuit Breaker(ELCB) was given to a device that breaks the power supply when a fixed amount of current ,say 25-40 milli amperes flow through the earth line. The MCB (Miniature Circuit Breaker) is a device designed to protect a circuit's wiring from the serious damage which would be caused if it has to carry a current which is too high for the diameter of the its wire
