3. Register with your email  on the top right of the page then login. 

4. Start using Schneider Electrical Calculation Tools (ECT)

5. Go to Cables page   >>>> Create cable c.s.a.   

6.Set Project parameters--- Load parameters ---  Cable input parameters- --- Method of installation.

7. Calculate cable c.s.a.

8. Go to Calculate  cable voltage drop page

9.Set cable input parameters

10. Calculate cable voltage drop---cable maximum length.

Very important note:

a. Print the  2 screens on a single sheet ( front and back)

b. write down your section,  your  number and your name on the upper right corner of the sheet.

Note:

Marks deduction were based on the following items (assumptions):

1. Bad printing quality

2. No name was written on report sheet

3. very light/heavy load assumption, e.g.   600W/100A

4. Short/long cable length assumption, e.g.    5m/60m.

5. Unacceptable  working ambient temp.  30 deg.C.

6. Very small v.d. means uneconomical solution.
