🤔 FAQs About Installing EV Chargers in Singapore Homes
Q1: Can I install it without an LEW?
No. According to EMA regulations, only a LEW can legally install and submit fixed EV chargers in Singapore.
Q2: Why not use a regular wall socket?
Using an extension cord or multi-plug for EV charging is illegal and dangerous. It can cause overheating, fire, or property damage.
Q3: Will my DB box need upgrading?
Our LEW will assess your power load. Older homes may require a DB box upgrade to support the charger safely.
Q4: How long does it take?
For most landed homes, the process takes 4–6 hours — including testing and submission. Larger setups may take longer if rewiring is needed.
