Hi all,

My new 'semi-d' house came with single phase electricity unfortunately and am currently exploring options to have it upgraded to 3-phase. From what I heard from my electrician, it seems that the supply from TNB to my house meter (at the front gate) is already 3-phase but this dumbo developer, for somewhat reason, pulled single phase from the meter to DB / house.

If I need to upgrade to 3-phase, need to hack the internal wires / cables in my house? Means from the meter all the way to the DB box? (in store room).

Thanks.
My DB box is placed in the store room and beneath it (on the cement floor inside store room) is a manhole cover with sands underneath. Any idea what that could be? A service pipe buried or hidden underneath?
