## Cable Calc Reviews in United Kingdom

### *---- "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.
-- unseasonal weather, 2024-03-23

### *---- "Works ok but ads are too distracting"
As above, would use it more if not for the bombarment of advertising nonsense.
-- Benlinds, 2023-12-05

### *---- "Very limited"
If you want to do anything big (>800A) then forget it.
-- North bollock, 2021-07-15

### **--- "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.

### *---- "No good"
20A single phase circuit, in singles installed in trunking, 75M and its giving me a cable size of 70mm 😂
-- dhjitrfbjkutgnko, 2021-01-28

### ***-- "Rich"
It good but needs ring /radial circuits allowance!
-- Mow2009, 2020-10-28

### ***** "Excellent"
Great fast calculating tool very accurate
-- Dayo17, 2020-05-04

### ***** "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.
-- Dj Edison, 2020-04-19

### *---- "D Evans"
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
-- dd sparky, 2020-02-20

### *---- "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.
