Frequent tripping of circuit breaker

In heartland Chua Chu Kang, the nuisance tripping of the earth leakage circuit breaker is fairly common, especially during thunderstorms.

Sometimes, entire Housing Board blocks are affected. And when no one is at home, all the food in the fridge will go stale.

What could be the cause of the trips?

With greater knowledge about the physics of lightning and advances in technology, hopefully HDB will upgrade its conventional lightning protection system for its ageing estates.

As residents are very worried about the problem, what is HDB's advice to those affected?
