TNB supply application for new & upgraded premises
Two routes from site visit to energising, decided by your maximum demand. We handle the contractor route for homes, shoplots and workshops up to 100A — load calculation, wiring to MS IEC 60364, Form G and Form H, myTNB submission, metering and handover. Above 100A we work alongside your consultant engineer on the installation, testing and meter application.
Process guide
Is your load up to 100A?
About 72 kVA on three phase, whole-current metering. Most homes, shoplots, offices and small workshops stay on the contractor route. Large commercial buildings, factories and plants above 100A take the consultant route.
Homes, shoplots & small workshops
Appoint a registered electrical contractor (registered with Suruhanjaya Tenaga). We handle this route end to end.

- Wiring, testing and certificates — installation to MS IEC 60364; Form G (completion) and Form H (test) issued.
- Submit on myTNB — signed application form, owner documents, certificates, site photos and location map.
- TNB issues connection charge statement — within 14 days for individual domestic applications (TNB Customer Charter).
