Cable Pro Cable Size, Voltage Drop & Maximum Demand Software
Cable Pro – Example Cable Size and Voltage Drop Calculations
1. What are the benefits of owning 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 onto one computer. A simple online 24/7 activation process is used. The software licence is easily deactivated by the user and moved between PC’s.
9. What if I want to move the licence to another computer or if my computer crashes?
You can easily deactivate the licence activations under the Help menu yourself and move to another PC.
10. Are there any ongoing fees?
After the first year there is an Optional fee to continue to receive Updates and Support (which includes unlimited licence transfers/deactivations).
11. Do you provide technical support?
Yes, please phone us on 1300 093 795 or email firstname.lastname@example.org. You can speak on the phone with our local technical support staff. We use an advanced email ticketing system ensuring all email enquiries are responded to in under 3 hours.

“Cable Pro is the perfect tool for our business as we are often faced with time constraints due to workload. It’s fast and very easy to understand. Reports can be quickly generated to allow comparisons with variations in the installation to give us the best result to suit our customers electrical supply/load demand.”
Darren Simpson – Midas Electricians Pty Ltd
“Very impressed with the software, we have used several other packages but this one suits our needs the best.”
Phil Hall (Director) – HiTech Electrical Automation
“Cable Pro has grown through our office, beginning with our estimation department, with now all our project managers, estimators and site supervisors using it on a weekly basis.
Cable Pro saves huge amounts of time identifying cable sizes, and conduit sizing as required. Reporting is easy, and the ability to customise our reports with our Company Logo is a huge benefit.
The support staff at Electrotechnik are very helpful and have always been available when needed.
I highly recommend Cable Pro for all Electrical Contracting companies.”
Trent Petersen (Director) – Cablewise Electrical & Communications Pty Ltd
I run a small electrical consulting business and I need to be as productive as I can possibly be.
This software (Cable Pro) has enabled me to cut out a huge number of manual calculations as far as maximum demand goes, especially for the larger jobs.
The max demand tables are built in and I do not have to consult the wiring regulations all the time while I’m busy with the design.
Furthermore, one can calculate cable and conduit sizing and voltage drop accurately.
It also takes care of earth fault loop impedance calculations which are often vague and difficult to calculate and ignored by some.
These calculations are saved with every job as part of my record-keeping.”
André Koorts (Director) – AK Consulting Ltd
“Excellent software. Excellent support. Highly recommended.”
G. Littleford – Electrical Contractor
“This software helps us to be more competitive. We can now bid for large jobs in less time.”
