Incorrect response

App developer stated in response that only SWA cable types can be installed on ladder or tray. This is incorrect, BS7671 Tables 4D1A & 4E1A permit installation of unarmoured cable on tray or ladder. Methods F&G. There are occasions where I do not want SWA cable. The App only gives an option for installation of unarmoured cables in or on wall.

Hi, In accordance with BS 7671 the permitted installation reference methods are dependant on the selected cable type, for example single insulated cables cannot be installed on cable tray. If you select an SWA cable then the relevant installation methods are shown for that cable type such as cable tray, free air ect…

Works ok but ads are too distracting

As above, would use it more if not for the bombarment of advertising nonsense.

There aren’t any ads in this app, think you have confused this with a different app as there isn’t any ads in this app.

Very limited

If you want to do anything big (>800A) then forget it.

Problems

On step 2, there is a problem where you can not select the ambient temp without clicking on the two options below first. This needs fixing. (It says “no option”)
To improve this app, it would be helpful to allow you to select the wrong cable, and tell you which part doesn’t comply, and then you “+1 size” until the cable is compliant, where as you can not see the information now until you “go up a size”.
I.e. if the volt drop was none compliant etc, this would be useful but I guess may be difficult (and maybe not what it was designed for). I just thought I would feed this back.

Hi, the ambient temperature options depend on your selected installation method (ambient temp or ground temp), hence why you need to select an installation method first and why the Installation Method option is before the Ambient Temperature option. - It the designers responsibility to select a suitable cable type for its intended use. - When calculating a cable size if something does not comply you get a hint "Volt Drop Compliance Not Met: Try next size up" or "Max Zs Not Met: Try next size up?"

No good

20A single phase circuit, in singles installed in trunking, 75M and its giving me a cable size of 70mm 😂

Response from developer

Other parameters also apply to calculating cable sizes such as Ze, max Zs, grouping and Volt drop, not just design current and cable length. For example if your Ze is 1.70 and your PD is 20A MCB type B the max Zs (80%) is 1.75 - therefor it will require a very large cable to satisfy the Max Zs due to a high Ze. Feel free to email us your calculation to support@pro-certs.com

It good but needs ring /radial circuits allowance!

Thank you for your feedback.

Great App

I personally have not had a problem with this app. It’s a really useful app for those who want to check cable requirements on the fly.

Worst cable calc app, tried getting the cable size for a 209amp circuit would not do it so I tried a smaller circuit and it recommended 16mm T&E for a 25 amp supply covered by a 32amp rcbo

Response from developer

Other parameters also apply to a cable calculation (other than just the rating) such as the Ze, max Zs, volt drop, cable resistance and installation methods. A high Ze or long circuit will increase the required cable size. Correction factors also have an effect on the cable size. Can you send your calculation requirements to support@pro-certs.com

Bugged

Despite carefully entering all the information and making sure all fields are complete the app keeps throwing out an error saying that there are missing values.
