In my reply to Nguyen post, I admitted my mistake in oversimplifying too much to
the original post. I'm could be electrical engineer too but won't admit it as
I'm doing too much software :-)
Paranoid mode on:
Quick Boys and Girls, start removing all your powerhead, canister filter, power
filter, internal canister or what have you got in your tank that directly use
main 110V supply. The main supply can leak to your tank any time and cause major
health hazard. The insulator may break. The impeller housing may spring a leak.
Your shark may bite the main cable in your tank that carry 110V. blah..blah...
I'm paranoid already ;-)
Paranoid mode off:
If the heating cable has been tested by electrical appliances certification
laboratory, then we can trust it, just like we trust our powerhead, heater etc.,
etc. The DIY is the one we have to worry about.
Paranoid mode back on:
rgds..KB Koh, the now paranoid guy in Malaysia who is right now rushing
back home to turn off all power to his fish tank.
