Topic: HELP! house ground...

[Zitr0]

greeting sir,

hingi lang sana ako ng help/tips on possible options sa pagpapagana ng proper 3point  outlet. tatanung ko sana kung may options bako na gawin to properly kung wala na ung traditional grouding rod na nakikita natin sa labas ng bahay na nakabaon sa semento papunta sa lupa? macoconsider po ba nating yung buong bahay would be grounded wherein any metal part might be used, like window grills, nails bound on walls etc?

BTW: may nakapag sabe saken na yung PLDT line daw may natural ground sa isang sa wire na nasa loob since 3 wires din daw yun, nkatap sa poste daw yun direkta? pwede ba yun talaga? kung pwede anung color yung normally sa wires kaya?


salamat!

If you can put in new earthing spikes, that would often be the best option.

Alternative options are:
1. Confirm if the neutral path from the Meralco split-phase supply is sufficiently grounded (and if there is not much potential between grounding locations). If so, this might be an option.
2. If your water lines are still made up of metal pipes that go under your house, you can check if this can be used as an adequate ground.
3. Tap on the nearest electrical post's earthing line (the thick cable that goes to the ground).

Do not use PLDT's neutral line. That conductor is too thin, and will present too much resistance in case of a fault.

Sir kung meron kang VOM (Volt-Ohm-Meter) sa bahay e you can check how much resistance yung reference ground mu.  An ideal reading is 2ohms and lower, masmaganda kasi na mababa yung resistance ng grounding mu para if in case may lightning na tumama sa house mu e dun pupunta yung current and not into your appliances.  Hope this would help.
