YOU ARE DOING A GOOD JOB , MOST OF THE PERSON DOES NOT TOUCH IT

[@electricalinindustry]

Thanks keep watching ❤️

[@adilakbar3053]

Thanks for sharing informative material Sir

[@electricalinindustry]

Thanks and welcome

[@anonymus7387]

This is the formula for cable sizing...not for sizing of earthing conductor. Please review.

[@mdafsar5058]

The above formula you have mentioned It is IS standard or British Standard

[@electricalinindustry]

IS

[@mdafsar5058]

Thank you for reply, could you please provide earthing conductor formula according IEC or British Standard

[@kakongkea7784]

Dear Sir Please kindly check about the method value calculation conductor sizing I'm following the method calculation below: - (Isc=25kA, K=205 for Cooper Conductor, t=0.5Sec) * We can use formula ((S=Isc*√t)/K) Therefore, S= ((25*10^3*√0.5)/205) =86.23mm² (We can use select follow in the table we have conductor sizing 95 mm²) Many thanks so much!

[@electricalinindustry]

Thanks for watching dear, for calculation kindly check the example again in video for small correction.

For home lightning arrestor, what should be the copper wire of down conductor?

[@electricalinindustry]

Dear it depends upon many factors.

[@SURAJPATIL-vg7mc]

Bhai I value load current lete hai

[@electricalinindustry]

No, short circuit current

[@mohitmeena1233]

Bhai aap pakistan Sai ho kya

[@electricalinindustry]

How may I help you

[@Akshaypawar-un9wl]

Is there any standard you are using?

[@electricalinindustry]

This formula is based on IEC 60364 Standard

Sort circuit cureent kese disid kre?

[@electricalinindustry]

Short circuit given hota h

[@md.anisurrahman8708]

What is the reference of this formula?

[@electricalinindustry]

This formula is based on the IEC 60364 standard.

LET US KNOW CABLE CONDUCTOR FOR LED LIGHTS INSTALLATIONS

[@electricalinindustry]

For LED lights installations, the earthing conductor size depends on the total current and fault current requirements. Here are some general guidelines: 1. For LED installations up to 10A: - 1.5mm² (14 AWG) earthing conductor is usually sufficient 2. For LED installations between 10A-20A: - 2.5mm² (12 AWG) earthing conductor is recommended 3. For LED installations above 20A: - 4mm² (10 AWG) or larger earthing conductor may be required However, it's essential to consider the following factors: - Total LED current - Fault current (if applicable) - Distance between LED drivers and earthing point - Soil resistivity (if earthing electrodes are used) - Local electrical codes and regulations

DO COMPLETE CALCULATION WITH PICTURE

[@electricalinindustry]

Sure

COMPLETE THE VIDEO

[@mdsadikhusain7007]

Sir If Someone ask me why time short Circuit 0.5 sec why not 0.10 sec what should be response?

[@charylucky9981]

All the materials designed for more than 0.5sec solar ,as a thumb rule to avoid the damage we have to maintain 0.5sec

[@electricalinindustry]

The time value "t" represents the duration of the fault current in seconds. This is the time it takes for the protective device (e.g., fuse, circuit breaker) to clear the fault and interrupt the current. Typical values for "t" are: - 0.5 seconds (500 ms) for fast-acting protective devices - 1 second (1000 ms) for standard protective devices

[@electricalinindustry]

❤️

[@transparentinfraandenergys5568]

Unable to understand as nothing is clear about cable ie copper or ALLUMINIUM armoured

[@electricalinindustry]

Both can be use but the size calculation will be different as described in video kindly watch again ❤️

[@manishkumargautam1654]

Very boring topic

[@electricalinindustry]

That's why I explained this in very simple mannar.

You must have basic knowledge
