What are the various factors to be considered in the selection and sizing of the cable for the application?
Cable size selection is based on three main factors:
- Current carrying capacity.
- Voltage regulation.
- Short circuit rating.
What are the factors to be considered while selecting a cable for a particular service?
Cable selection can be based upon the following five key factors:
- Cable installation.
- Cable construction.
- Cable operation (voltage and current)
- Cable size.
- Shielding requirements.
How do you determine the proper wire and cable size for electrical wiring installation?
Solved Examples of Proper Wire & Cable Size
- Total Load = 4.5kW = 4.5 x1000W = 4500W.
- 20\% additional load = 4500 x (20/100) = 900W.
- Total Load = 4500W + 900W = 5400W.
- Total Current = I = P/V = 5400W /220V =24.5A.
Is standard for cable sizing?
The cable sizing calculator calculates the cable size based on current rating, voltage drop and short circuit current according to IEC 60364 and HD 60364 standards. IEC 60364 -Electrical Installations for Buildings, is a harmonized standard that has been adopted by many countries in the world.
Is standard for XLPE cable?

Which one of the following size is not a standard cable size?
Metric AWG Conversion
| Number strands/diameter per strand | ||
|---|---|---|
| mm² | Awg | inch |
| 16 | 1/.0508 | |
| 16 | 7/.0192 | |
| 1.5 | 1/.055 |
Is it OK to oversize cable?
Using larger gauge AWG wire offers you more flexibility in how your electrical system is laid out. Your electrician can add more outlets when your wiring has increased current potential. Larger wiring can sometimes be installed in risky areas where small wiring is not recommended.

Why choose XLPE insulation?
XLPE is well established, cost competitive and doesn’t have any of the degradation or fire related issues of other insulations. You will also end up with a smaller cross sectional area. Only in special circumstances would you need to look at other installation types.
How do you evaluate a new cable?
To evaluate these situations, one of the best things is to understand fully the characteristics of the load the cable will be supplying, the environment it is being installed in and be aware of other overriding issues. If you can do this, any necessary adjustments to the eight point plan often become apparent.
