Question 1

I have this installed but the (red) LEDs are off/dim. Does this need to be replaced? It is approximately 12 years old.

Accepted Answer

If one or two LEDs are out that indicates the breaker is no longer working and the circuits they supply must not be hot (useable).  Check the two breakers with a voltage tester to be sure.  Being in service for 12 years circuits may have seen the voltage spike and tripped the breaker.  If they had been installed properly these two circuits would have fed voltage/current to circuits that were in use.

Question 2

Does this offer the same level of protection as the SF100? One review said that the SF100 protected the "sensitive electronics" better.

Accepted Answer

The Seimens protects nothing. I know personally. I had a lightning strike and lost $20,000.00 worth of Electronic equipment TV's, computers, printers and a multitude of other appliances. the Siemens unit was still glowing green as nothing had happened. When I contacted Siemens about their warranty I was informed it would only cover the wiring in the walls if it was damaged and nothing that was plugged into the outlets. Don't waste your money, they don't work at all and their warranty is very misleading.

Question 3

Will this fit an ITE panel?

Accepted Answer

Perfect fit in ITE EQ panel.

Question 4

Can a load be connected to this protection device, such as a clothes dryer or does this need nothing attached?

Accepted Answer

Yes a load can be connected to the unit and it is designed for that.  My understanding is not a double hot leg (220-240 volts) only 2 separate single leg loads (120 volts).  There are 20 amp and 15 amp versions available as I recall.  In short you check on your panel that you have 2 single breakers either 15 or 20 that are next to one another (or can be placed next to one another) and replace them with this unit.
