I had a desparate phone call from my son in Kuala Lumpur, Malasia.
The main isolator in his consumer unit had tripped, he had no power and there was funny smell coming from the unit.
With no airconditioning in his 5 bed apartment the temperature was becoming unbearable.
He had called an electrician but nobody could come and fix the problem for at least 6 hours.
I told him to try remaking the breaker but it just tripped again and more smell.
The Malasian electrical wiring system is identical to the UK by the way.
Anyway the electrician eventually arrived and fixed the problem.
Can anyone guess what the problem was? Very unusual but no prizes.
I will tell you tomorrow.
