Its All About The Plugs.

Ok this is so random.

But since my page has been pretty quiet, maybe Ill talk a bit about extension plug.

For this case, surge protectors.

I know for sure, the number of wall outlets in our homes these days ain’t enough to power all our devices.

As such, we have these extension system almost in every part of the house.

Do we need surge protectors? My advise; yes.

Do we need good ones, even with circuit breakers (aka RCCB)? My advise; yes.

Should RCCB trip when there is a sudden electrical hazard scenario? Yes, BUT there are still chances some amount of surge or spike has passed through your electrical circuit, and ta-daa! It probably has done some damage to your equipments.

How about fuses? Yes, they blow when excess current passes through them, BUT most extension plug have been equipped with a 13A fuse. Tell me when do you use 3250Watts at a single time?

(When you have about 3 irons running on the same extension, or 2 vaccum cleaners? Make matter worst, some adapters are NOT even fitted with a fuse these days.)

Surge protectors, just like most fans, have an extra safety fuse called thermal fuse, which melts when the cable runs too hot.

Ok. In short, if you need an extension plug, purchase one with true surge protection. Most in the market these days claimed to have one but there are no written evidences such as surge protection values (usually written in joules, amperes rating of the MOVs).

Also, some have LED indicators, which is an added feature to tell you when protection has worn out.

Some even has line filtering (i.e. EMF reduction) features, which is good though most devices have adapters or converters that does this ‘electrical signal cleaning’ before it powers the actual device.

Higher end products have ADSL and/or coaxial cable protection as well; do use them for full protection.

So, Im quite fanatic about this, thus these are my trusted Belkins around the house.

01. Belkin Advanced and Gold series

The one above is utilized to protect my DECT phone, and the telephone cable line (RJ11).

The higher end Gold series are used to protect delicate equipments, as well as provide more power point outlets.

02. Belkin Economy series

These are cheaper ones, but should provide trusted power for the less delicate items at home.

Ive used them for months for my house TV, router, DVD home theatre systems, and well, it worked well living through multiple stormy weather.

Ok, here is an added advice.

Daisy-chaining extension on another?

Yes. I know. Its dangerous. But my old workplace has inadequate wall points. And these are used to power just USB power adapters/chargers.

Well, 5V to 2A, per adapter it uses 10watts only, right?

And yes, they claimed to have surge protection as well.

Though not advisable, what if you need to?

For me, I strongly do not recommend, but for those die-die need to have cases, I make sure that:

  1. Never connect 2 or more surge protectors along the same line together
  2. Maximum load should be less than the first extension limit (i.e. if the main extension plug supports 13A, Ill make sure everything on the plugs daisy-chained together uses way below; maximum 13A on 250V is 3250watts but I limit it way below to 2000watts)

Be safe people.

Check your plugs regularly, do not overload, insert them plug head properly, and replace when required.
