    Electrical ELCB Frequent Trips

    Guys - just to highlight an incident at my home recently

    Had the ELCB frequently tripping and got really annoyed and irritated with it - Called an electrician friend and this is what he said

    "if you reset the ELCB and it trips again, try bringing down all the MCBs (mini circuit breakers) and then reset the ELCB.... after which reset the MCBs back in place.... if the ELCB 'doesn't immediately' trip ~ then big chance you have a NEUTRAL short-circuit....."

    "most likely culprits are one of the fluorescent chokes (ballast) or a recently added extension cord/wire"

    "remove extension wires and cross fingers... if it (after a while) STILL trips, then check choke/ballast"


    so I did just that... checked the chokes and guess what - the chokes were ALL brittle and flaking... so I got ALL of them changed.... and
    so far - the last 72hrs.... NO MORE TRIPPING!!

    I've realised that these chokes have had been up in the ceiling for the last 10 years+ and had never been changed... With the generated heat - it's a wonder they lasted so long....

    Cost of replacing all the 10 chokes (upstairs) RM6.00 x 10 pcs = RM60.

    ps:
    Quote from electrical center somewhere in USJ .... "Kena check dulu... agak agak, RM400 boleh cari itu ploblem..." .... ya rite...

    Obviously you incurred a real "earth leakage problem". This is a common fault anywhere when there's use of local made florescent fittings. Our local made chokes and fittings are INFERIOR!..you get what you pay for, and never think it last more than a decade. I really don't know how SIRIM can approve these things for retail. Of course easy to point finger and say there's bloody cor*****n or malpractice. The onus is on you to use better made stuff, if can afford it. They're far safer and better safety factor. Lucky your ELCB works and it did its job, otherwise you may be in for far worse disaster if those things catch fire.

    BTW, do add a little capacitor to all those florescent light fittings, it improves on power factor and consumption. In other words, you may consume a bit more electricity for given consumption. Yes, another few bucks each!

    Not to mention your "newly changed TNB Meters" are very sensitive to current consumption. Its not as lossy as those previous electro mechanical meters. EVERY BIT of current consumed IS NOW charged TO YOU! (or to your disappointment).

    Mine is still using the old "spinner" discs ones... so sitting pretty for a while...

    Anyway, back to the "choke/ballast" story... me dunno much about the capacitors but from the looks of what I have done, damn thing is solved (no more tripping) and now will wait till the next 10 years or another Mayan calender to end...

    Right!. they look like little black plastic square package or cylinder with 2 wires. Just connect them across the live and neutral connector, you're done. Where to get them? good electrical stockist or electrical supplies store. They're not expensive but at DIY stores can cost a little more. One is required for each lamp. Of course, if you're not into DIY, a general electrician can fit them for you. It doesn't wear out, last a lifetime. Its usually called a lighting capacitor, or florescent light capacitor.

    I have asked an E&E engineer friend about these, he said it reduced 'Eddy current' (whatever that is) which is generated by appliances running motors ie fans, aircon, fridge, washing machines & vacuum cleaners. Not effects on lights.
