Firefighters responded to a power surge affecting multiple properties in an area from Braemar Road to Imperial Road in Wood Green.
The power surge originated from an electrical sub station and caused consumer units to overheat. Crews attended approximately 100 properties to check and isolate the electrical supply and give advice to residents.
Due to the high volume of calls to our 999 Control officers introduced batch mobilisation, meaning calls where there is a risk to life are prioritised and crews then attend other calls as non-emergencies when they can.
The Brigade was called at 0055 and the incident was under control by 0222. Crews from Hornsey and surrounding fire stations attended.
