Cable Pro Cable Size, Voltage Drop & Maximum Demand Software
Cable Pro – Example Cable Size and Voltage Drop Calculations
1. What are the benefits of the software?
Cable Pro (PC) will save you time and money by helping you choose the most economical cable sizes. Complex electrical calculations which by hand take hours or days to perform can be done accurately in minutes or seconds.
2. How easy is the software to use?
ELEK software is designed to be very easy to use. Some basic user input is required and then the software will automatically design in compliance with the standards.
3. Is the software suitable for solar applications?
Yes, the software includes a d.c. supply setting for calculations and for up to 1000 V d.c.
4. Can the software be used for high voltage?
Only up to 1 kV or 1.5 kV for solar (d.c.). For HV cables have a look at our other software Cable HV Software.
5. Is this software up-to-date with the latest Standards?
Yes with the latest Australian/New Zealand Standards and their amendments.
6. What if the Standards change?
The standards change occasionally, usually every few years. When the standards do change we will update the software within 6 months, which is the expected time for everyone to comply. The software itself will notify you during its use or you will be contacted via email of a new version being available for download.
7. How is the software delivered?
Via instant download. Link to download, activation code and invoice emailed immediately (24/7) after purchase.
8. How is the software licenced?
Each licence may be activated on up to two computers. A simple online 24/7 activation process is used. The software licence is easily deactivated by the user and moved between PC’s.
9. How many computers can I use the software on?
You can use each licence on 2 computers. For example a desktop and a laptop.
10. What if I want to move a licence to another computer or if my computer crashes?
You can easily deactivate the licence activation under the Help menu yourself and move to another PC.
11. Are there any ongoing fees?
After the first year there is an annual fee to continue to receive updates and support (which includes unlimited licence transfers/deactivations).We regularly update our software, not just for new Standards, but to add new features and improvements.
12. What happens if I stop paying the annual renewal fee?
If you choose to opt out of annual renewals, your software will continue to work, but you will not be eligible to update to the latest software versions as they are released, nor contact support for assistance. (Please keep in mind, that updates are essential if you want to stay up-to-date with the latest Standards.)
13. Do you provide technical support?
