Why Getting the Right EV Installer Matters: A Real-Life Case This Week

What Happened: A Cautionary Tale from a Real EV Charger Installation

One of our customers recently had his home EV charger, Zapzoom load balancing charger professionally installed by our certified team. A few weeks later, he invited a solar panel company to explore solar system installation. During the visit, the solar installer looked at our charger setup and claimed something was wrong.

Their concern? That the charger’s power was tapped from the ELCB (Earth Leakage Circuit Breaker) — which they said was incorrect. According to them, it should have been connected directly to the incoming supply.

This feedback alarmed the homeowner, who immediately reached out to us, worried he might be at risk.

But here’s the truth: That advice was not only wrong — it went against Malaysia’s official EV installation guidelines.

Suruhanjaya Tenaga Guidelines Say Otherwise

As per Suruhanjaya Tenaga (Energy Commission) (ST), Malaysia’s energy commission, tapping power for EV chargers from the ELCB is the correct and regulated method.

Why does it matter?

Safety – In the event of leakage current or over current, only the EV charger will trip — not your entire home’s power supply. Protection – Your electrical appliances, home system, and loved ones are better protected. Compliance – EV installations that don’t follow ST guidelines can void warranties and fail inspections.

Had the installer tapped directly from the incoming power — as the solar contractor suggested — any fault could cause the entire house to lose power in the middle of the night. That’s a serious inconvenience, and a safety risk.

This situation is a reminder of why choosing the right EV installer is so important. Here’s what you should check before hiring one:
