Architectural Graphic Standards 10th Edition: 10'-0" Minimum unobstructed clearance around court
The minimum required clear space on a basketball court depends on which kind of court it is. An NCAA court has a minimum of 25', while a recreational facility's minimum is 20'.
As for as I know, the clearance is based on voltage. For 415V AC the minimum clearance required between phases as per standard is 19.5mm.
You must give the cyclist 3 ft of clearance between your car and the bicycle.
To ensure that the minimum height of their conductors maintain the legally-required clearance above ground. The greater the operating voltage, the greater this clearance must be.
This varies by state and local codes, although most use the NFPA codes. Google: NFPA minimum clearance woodburning stove
The minimum electrical clearance is the minimum distance between electrical conductors with different potentials (voltage). This generaly determined by the maximum possible voltage differenge between the conductors. Dimensions larger then the minimum electrical clearance are OK, however smaller dimensions start to risk arc-over between your conductors.
