He also wanted a separate isolated and insulated equipment grounding conductor for each circuit.

He wanted to install EMT from his service panel to the media room panel and to four separate metal boxes in the room with a single 20A, 120V dedicated circuit in each box. In the end, he relied upon the information I gave him, along with his electrician, to perform a safe installation.Īccording to my interpretation of his email, the homeowner had a service panelboard on the outside of the house and wanted to install a six-circuit panel in his media room with four dedicated 20-ampere (A), 120-volt (V) circuits to supply the audio/video equipment. He found an article I had written for ELECTRICAL CONTRACTOR on isolated ground receptacles and circuits, so he contacted me to see if I could clarify the project and get him on the right path. In addition, the electrician friend and the audio company engineer provided conflicting information and the homeowner was having trouble understanding the manual. The audio equipment manufacturer provided a 65-page instruction manual with diagrams and illustrations to help with equipment installation. He also contacted an electrician friend, the audio/video equipment manufacturer from whom he had purchased his equipment, and an audio company engineer. Before doing the installation, the homeowner had conducted internet research on the background requirements for audio/video installations. I recently received an email from a homeowner who was installing a high-end media room and had questions about his home’s electrical system and the new circuits for the audio/video equipment.
