ECN Forum Forums General Topics of the Trade General Discussion Area What harm in no grounding electrode?

Grounding and _bonding_ can have a significant effect on things inside the house. Spend some time reading past threads in this section of the discussion board, or the Grounding and Bonding section of the Mike Holt board.

IMHO you should double check for proper bonding between any signal lines coming in to the entertainment center (eg. the CATV line) and the electrical system.
