somac just called me this evening and asked me a few questions about the Cal-Lab devices he had.

First, let me explain a bit about cal-Lab devices and so, this is going to be quite long winded....

Cal-Lab Devices are very different from the normal lightning arrestors. A normal lightning arrestor diverts the strike to the ground whereas Cal-Lab isolates your equipment from the strike to prevent further damage. In both cases, earthing is very important, more so on a Cal-Lab which uses your Home's earthing electrical system.

Since every genuine Cal-Lab device has a warranty of some kind, it is best not to open it up and go to Pasar road for replacement components although in theory, you can. But then, Cal-Lab would know and this would void your warranty and whatever claims from your insurance, etc. I mentioned genuine because a few years ago, Cal-Labs were copied and was very common in Pasar Road and electrical shops.

When your Cal-Lab device fails all the time, perhaps it is good to check on your electrical Earthing. If it plugs to your telephone line, then it is also time to check on that earthing too since both Earthing are different. When a strike/surge is extreme, a Cal-Lab device will fail and don't worry, it is meant to do that. Think of it as your equipment's bodyguard.

Lastly, there is a lot of different versions of Cal-Lab so make sure you get the correct one. Eg There is a version for Astro, Streamyx and also, phones. A wrong one usually means dropped connection from your Streamyx. It is very sensitive to voltage changes too. For a phone version, I usually use those Cal-Lab replaceable cube modules as this works great when I was in the Phone Industry.

Back when I was working for the customer service division of a Japanese electrical appliance company, Cal-Lab isolators were pretty much the default surge isolator.

Our service centre also provided the service of collecting and replacing 'expended' isolators and recycling them through Cal-Lab for repair & rework.

Definitely one of the better products of its type.
