Toronto Building's declaration on clearance to overhead electrical conductors, signed by the designer who prepared the drawings behind a building permit application for a new building or an addition. Section A prints Article 3.1.20.1 of Division B of the Ontario Building Code in full, with horizontal clearances of 1 m, 3 m and 3.7 m stepped by conductor voltage, and points to Toronto Hydro for conductor location, voltage and maximum swing. Section D holds two alternative declarations: conductors buried underground, or clearances that comply.
