This may be a bit off topic for an EV forum but the company that will soon be installing my charging point intends to use Hi-Tuff cable rather than armoured cable (SWA). I wouldn’t be concerned about this but there is a short underground run and when I dug the 500mm deep trench for this I exposed a few tunnels caused by rats. I know that rats will chew cables and I’m not sure if they could gnaw through the Hi-Tuff more easily than SWA? Yes - getting rid of the rats would be ideal but it’s near a chicken run and a compost heap and in 25yrs I’ve never managed to eliminate them altogether. I’m not sure if there’s a flexible rat proof conduit available or if burying in concrete might harm the cable?
