Main information
What it could mean
A damaged cable (stripped, cut, chewed, or with degraded insulation) creates a risk of direct contact or a short circuit at the affected point.
Safety first
Don't touch the damaged section of cable. If possible, stop using that circuit until it's repaired.
Next step
A visibly damaged cable always needs the affected section replaced; it's not advisable to temporarily wrap it with tape or other DIY materials.
Frequently asked questions
Is a cable with slightly worn insulation dangerous?
Yes, any exposed part of the conductor is a risk of direct contact; worth treating as a priority.
Can I insulate the cable myself with tape while I wait?
Not a safe or lasting fix; better to stop using that circuit until it's repaired.
Does all the wiring need replacing or just the damaged section?
Usually just the affected section is enough, unless the rest of the wiring shows similar wear.
