Troubleshooting Home Lighting Problem

Click For Summary
SUMMARY

The forum discussion addresses a recurring issue with home lighting where light bulbs, both incandescent and energy-saving, blow out shortly after being switched on. The user reports that the bulbs exhibit an intense bright light for a brief moment before failing, suggesting a potential electrical fault. A possible cause identified is "Floating Earth," which may indicate an imbalance in the electrical phases of a 220V utility system. The suggestion to pour water on the ground stake is mentioned as a potential remedy for grounding issues.

Hi Guys.

I have a problem at home, and it's confusing me!
My light bulbs are blowing, not just the filament fusing, but the whole base EC and BN are also arching through!
Only when we switch on the light bulb, not when it already burning (on).
It has an intense bright light for a split second, then blows!
After replacing the bulb, it works fine for a week or so, then blows again!
This happens with incandecent and energy saving lamps!

A friend told me it could be, Floating Earth!
But I can't make any sense of Floating Earth!
Anyone with advice or a explainition on this fault, or Floating Earth?

Your utility may use Earth as neutral return. This can cause an inbalance in the two phases of a 220 utility. You might try pouring some water on the ground stake, if that's the case.
