earth circuit

Grounding sets connected to earth circuit are installed at each end of the circuit, to ensure the current circulation and the user safety as well.

If any 'open' circuits exist anywhere in the guitar's earth circuit a buzz will be noticeable - even with humbuckers - at the sort of mega gain you're talking about.

The equipment shall have a measured resistance of the protective earth circuit, or the earthing conductor of an extension cord or appliance cord set, which does not exceed 1Ω.

The earth circuit is modified when an ELCB is used; the connection to the earth rod is passed through the ELCB by connecting to its two earth terminals.

Generally it is not a good idea to use circular polarisation for earth circuits where the arriving polarisation is random, as there will be a -3dB loss (half power) compared with a single plane polarisation of any kind.

The earth circuit cables for the batteries and for the battery contactors pass through the lower part of the forward pressure bulkhead and rearwards through the lower fuselage, outboard of the nose landing gear bay side beams.
