SHAH ALAM (Bernama): The 30th witness in the murder trial of former Cradle Fund CEO Nazrin Hassan (Photo) told the Superior Court here that it was difficult for him to determine whether the fire in the victim’s bedroom was caused by an electrical problem.
The deputy director of the Energy Commission (ST) for Selangor and Kuala Lumpur, Abdul Rahim Wan Chik, 38, said that this was because the Fire Department had removed all the electrical appliances from the room at that time, with all plugs also sealed.
However, the inspection found that the two-story home was equipped with two three-phase electrical distribution boxes.
“The investigation also found that the electricity load supplied to the burned room was normal (adequate),” he said when questioned by DPP Ashyraf Ashy’ari Kamaruzaman before Judge Datuk Ab Karim Ab Rahman on Friday (December 18).
When asked how short circuits could occur, Abdul Rahim said that it usually happened when a neutral wire came into contact with the live wire.
Ashyraf Ashy’ari: Can a mobile phone charger cable be short-circuited?
Abdul Rahim: In the mobile phone wire, there is neither live nor neutral wire. Electronic equipment uses direct current.
Ashyraf Ashy’ari: If there is a short circuit, what will happen to the distribution box?
Abdul Rahim: Generally, the miniature circuit breaker (MCB) protection system in the distribution box will “trip” to cut off the power supply.
Ashyraf Ashy’ari: When the MCB system cuts the power supply due to a short circuit, is there a possibility of a fire?
Abdul Rahim: No, because the trigger time is very fast, that is, less than 40 milliseconds. Based on the test performed on the distribution box on the top floor of the house, we found that the “trip time” was 18.31 milliseconds.
Ashyraf Ashy’ari: On June 27 (2018), what did Mr. Rahim investigate?
Abdul Rahim: I performed the residual current device test on the upper and lower floors of the house and found that the protection system of the distribution box was working.
On March 12, 2019, Nazrin’s wife, Samirah Muzaffar, 45, a former senior executive of the Malaysian Intellectual Property Corporation, and two teenagers, 17 and 14, along with an Indonesian national, Eka Wahyu Lestari, who is still at large, they were charged. with the murder of Nazrin.
It is alleged that they committed the crime in a house in Mutiara Damansara between 11:30 p.m. on June 13, 2018 and 4:00 a.m. on June 14, 2018.
The trial continues on Monday (December 21). – Bernama
