CEC sells surge suppression equipment which helps protect against damage by power surges to sensitive electronic equipment. Many factors can cause momentary surges, but the one you are probably most familiar with is lightning.
The meter-base surge suppressor sells for $145 with a $25 installation fee. Additional plug-in surge suppressors may be purchased by CEC members to install on indoor electronics.
For consumer safety and to ensure proper installation, CEC employees must install the service entrance device. As part of the installation process, CEC employees test the ground resistance to make sure that it is within the proper range.
