Grounding(electrical)

[joemarski]

icic. In any case it seems dicey to involve the sprinkler or any other pipe for grounding. Baka maground pa yung ibang maintenance people.

Me earth ground naman daw bawa't floor ng building; we asked the contractor to install the ground wires going to our unit.

Yung equipment papuntang grounding "contact", pwede na pong stranded ang gamitin?

Each unit / offices inside the building is usually provided with a dedicated Electrical Panelboard/s.
May mga Grounding Bus Bars (GBB) sa loob ng mga Panelboards. These GBBs are connected to the
Main Grounding Bus Bars (MGBB) of the building. Kaya merong "Tapping Point" ang MGGB sa bawat floor.

Hindi ko masyadong maintindihan 'yung sinabi mong "we asked the contractor to install the ground wires
going to our unit". Ano 'yung unit? Office ba o 'yun mismong equipment?
Anyway, the nearest grounding point source will be the GBB inside the Panelboard.
I don't think that they will allow you to tap your grounding wires to the MGBB of the building.
Ina- alala ko kasi kung saan nag tap ang contractor mo, at saka mahal na ang "wires".

Yung equipment papuntang grounding "contact", pwede na pong stranded ang gamitin?

Yes, stranded wires are the best to use. Use Terminal Lugs for easy / clean installation.
