1. It’s the Law
Regulation 75 of the Electricity Regulations 1994 requires that anyone performing electrical work holds a valid certificate of registration as an electrical contractor. Tenaga Nasional Berhad’s (TNB) customer guide echoes this, advising homeowners to engage an ST-registered contractor for site inspection and installation. Using a non-registered installer can result in non-compliance and void warranties.
2. Safety and Compliance
EV chargers draw continuous high current (commonly 32 A for a 7 kW unit). ST’s EVCS guidelines require that they be connected via a dedicated final circuit with appropriate cable size, overcurrent protection and residual current protection. Using a standard 13-A wall socket or extension cord is not safe and may cause overheating. Registered contractors know how to design and install these circuits correctly, including selecting the right miniature circuit breakers (MCBs), residual current devices (RCDs/RCBOs) and surge protection.
3. Warranty and Insurance Protection
EV charger manufacturers and home insurance policies typically require installation by qualified, licensed personnel. Installing a charger through an unregistered company risks voiding warranties and insurance coverage because the installation may not meet safety standards or documentation requirements.
4. Transparent Costs and Long-Term Reliability
Registered contractors are accountable for the entire project—from load assessment and cable sizing to proper earthing and issuing Form G (supervision) and Form H (test) certificates. They provide transparent quotations showing equipment, labour, cabling and protection devices, and they won’t cut corners by omitting essential components such as RCDs. Unlicensed installers might offer lower prices by skipping safety devices or using undersized cables, leading to frequent tripping or fire risk.
