Home owners may have noticed in their homes there are often quite large looking green and yellow coloured wires (cables) connected to the mains water pipe, often under the kitchen sink. There are similar cables connected to the mains gas pipe as well, if there is gas in the house. Are they important to electrical safety? well yes most definitely. In situations where there is a fault in the house electrical system or the importantly the electricity supply system outside the house, then these cables are to help protect the persons in the house from electric shock and the home itself from fire risk.
One problem I find is these connections can become loose or broken and occupants of the home could well not even notice. These connections could be improperly made and left for many years unattended to. If one of the cables is loose, broken or has a poor connection then under normal circumstances those living in the house would notice no difference in the electrical supply to lights and sockets. But if these was a fault then a dangerous situation could occur.
These cables and connections are important for home electrical safety. If a home has any electrical changes such as a socket moved or a light switch moved then a qualified electrician will always first inspect these cables to ensure all is OK. If no electrical installation additions or changes are made on the property for many years then a Periodic Inspection will spot any problems. Periodic Inspections should usually be performed no less than every 10 years on a Domestic property.
Do not remove or tamper with these connections. They are labeled with Electrical Safety Connection Do Not Remove.
If you notice any damage or disturbance of these green and yellow cables clamped to pipes then call in an electrician to have a look.
Arrange with an Electrician for a Periodic Inspection of your home at least every 10 years. Note there should be a label on the home Consumer Unit (Fuse Box) stating when the next inspection is due.
