MCB overload test

MCB overload test
• MCB is a protection device to protect wiring
installation against:
1. Overload current
2. Short Circuit current
In order to achieve perfect overload protection the
normal current of the MCB (Im) should not be less
than the design current of the circuit (Ic) and that
(Im) should not exceed the current-carrying
capacity of the conductors (Iw), and that the
current causing effective operation of the
protective device Itm does not exceed 1.45 times
the current-carrying capacity of the conductor Ic.

Bhot hi knowledgable video he, house wiring karte samaye sabhi batain dhayan me rakhna jarrui he. Me sabhi student, or
Jo House wiring technician he unhe recommended karunga. 👌

hello i like your video kan you make one with a 32c AC mcb with In 1.45 times

[@practicalvstheory]

Ok your desire will possible soon with 32A mcb

Sir ye jo adjustable amp ki divise he wo kaha milti he

[@sdfdgsdv]

FOR AC THAT IS CARRYING 10.69 A. WHAT SIZE AND TYPE BREAKER SHOULD I USE?

[@practicalvstheory]

Single phase ya 3 phase ha ac

[@sdfdgsdv]

@@practicalvstheory SINGLE PHASE

[@practicalvstheory]

16 ampere DP MCB because if AC compressor ON it will take full ampere current ampere in starting.
But if starting current of compressor is high above 16 ampere DP so big size DP mcb should use

[@sdfdgsdv]

@@practicalvstheory IN THAT I CAN USE C TYPE MCB. IT TRIPS AT1 SECOND WHEN CURRENT IS 6 TIMES MORE.

[@practicalvstheory]

That case mcb trip in magnetic protection (short circuit) it trip intstant according to characteristic curve
But if your current level not too much less than Or equal 1.45 time it trip in thermal protection ( overload)

भाई साहब, घरेलू यूज में मीटर के तुरंत बाद जो ड्यूल पोल एमसीबी लगाएं वो B40 लगाएं या C40 ???

[@V98000]

जवाब तो दीजिए...

[@practicalvstheory]

B 40 - sensitive loads very long circuit runs
Examples :Incandescent lights, Heater, Geyser
C 40 - General, light and power
Example : Fluorescent lights, small motors , Fans,
Refrigerators , window/split ACs
