Hi TB3 👋 welcome back to the community! Thank you for posting to let us know about this external wiring issue.
It sounds as though you may need a rebury appointment to sort any potential issues with exposed cabling outside. It is difficult to confirm if this is exactly as it should be as we can't see your property or cabling. On this basis it's best if we get someone booked out to you to rebury the cable if needed! I will send you a PM to confirm a few account details so we can get this booked in for you.
You will find the PM in the top right corner of the page in your Inbox. 📩
We can then return to this public thread with an update when possible. Thank you for your patience in the meantime!
Wishing you all the best. 🌞
