Electrical panel

Suggestion for an older electrical panel:

Hire an electrician to tighten all the connections in the electrical panel. The subtle earth vibrations can, over time, cause the electrical connections to become loose. A loose connection can cause power line noise and decrease DTCD. Replace the circuit breakers that provide power to the home entertainment system. These can develop carbon deposits due to arcing when the circuit is tripped.

Suggestions for a new electrical panel installation:

Virtually all home circuit breakers are thermal breakers. There is another class of breaker called hydraulic electromagnetic breakers. They are very expensive and can only be used in certain types of electrical panels. Coordinate with your electrician and electrical supplier to attempt to obtain this type of panel and breaker. You only need to use the electromagnetic breakers on the circuits that power the home entertainment system. Common thermal breakers can be used for the other power circuits.

Over-rate the power circuit. Install 20 Amp circuit breakers instead of the commonly used 15 Amp breakers. Even if your system does not require more than 15 Amps of current, the dynamic current headroom is valuable to system performance, especially when the home entertainment system has high power amplifiers.

There are two phases of power in a typical home power system. When a home is built, the electrician will divide the individual circuit breakers so to create an electrically balanced load between the two phases. It is preferable that the home entertainment system is powered from the phase that has the least noisy components on it. Avoid fluorescent lighting, microwaves, refrigerators and other appliances that cycle on and off.

Ensure that all electrical connections are tight and secure. Ask the electrician to come back in a few days to retighten all the connections. Copper wire is soft and pliable which will cause the screws to loosen up.
