Talk to the hall before the board trips

The quickest way to book a bay, a rewind slot or a scan round is a short message with the breaker serial and the board it serves. If you do not have those details yet, describe the symptom and the engineer will ask for the rest.

The form opens your own mail application with the details already filled in. If nothing opens, write directly to info@nertelenergy.buzz or call +17319373354.

Before you call

Three questions the desk hears most

Bring the breaker itself if it can be removed safely, plus the serial number and, if you have one, the outline drawing or the previous test sheet. If the board cannot be isolated, call first and the hall will send an engineer to the site instead of asking you to pull the unit out.
A coil that reaches the run before ten in the morning is normally back on its breaker the following day, because the varnish bake runs overnight. Coils that arrive later join the next bake and get an honest date on the intake ticket rather than a promise the run cannot keep.
Yes. The hall serves commercial buildings across Kowloon and Hong Kong Island, and small plants in the New Territories. The emergency rota response promise of two hours applies to contracted boards inside Hong Kong, and the desk will confirm the coverage for a new site before the first scan round.

Find the hall by the long wall of bays

The switchgear long hall sits on the twenty fifth floor of Wealth Coml Ctr on Kwong Wa Street in Mong Kok. Visitors should call ahead so a bay and a lifting frame are free when they arrive, and so the desk has the board drawings on hand for the conversation.
