It sounds like you have PRIMARY surge protection on your meter to protect your hardwired appliances (furnace, A/C, dishwasher, garbage disposal, etc.) against surges that come in through the electric meter. Not all surges that enter your home come through the electric utility. They can come in via telephone and cable lines as well. Therefore, you need SECONDARY protection on any electronic equip. that you value. You need to be sure that the telephone lines for your computer and coaxial lines for cable/satillite also go through the surge protector. This is frequently overlooked. For more information on surge protection see the September issue of the POA Bulletin that can be found on the POA4US. org web site under Lightning Matters, page 18.
