I recently have come across a spate of electrical supply problems when carrying out electrical safety checks for customers that want to upgrade their consumer unit or are buying a new house or selling one and it just reinforces the guidance on having a registered electrician inspect, test and maintain your installation periodically.
The NIE network in Belfast is very old in some places and the old underground cables have been deteriorating for some time now.
Even if you have the best protection installed in your fuseboard, if the supply characteristics are not within industry standards then your safety devices like fuse and circuit breakers in the event if a fault may not disconnect the electricity quickly enough to prevent danger from electrocution. Unfortunately this problem does not stop your circuits from working and can go unnoticed until tested, and as usual with most things if people cannot see that it is broken they will think there is nothing wrong.
It is recommended that domestic properties should be inspected and tested every ten years, rentals and commercial every five years. My advice would be to check when last you had your system looked at as with anything it will deteriorate over time and It could save your life or damage to the property. If you would like any more advice regarding electrical safety checks please get in touch. #whichtrustedtrader #niceicapprovedcontractor #yourlocalelectrician
