A non-polar covalent bond occurs when the electronegativity of the two atoms is the same.
'Polar' is when the electrons are more attracted to one atom than to the other, so 'non-polar' is when the electrons are attracted equally to both atoms.
This is what happens when two atoms of the same element form a covalent bond e.g. H2, but it also happens with atoms that are of different elements but have the same electronegativity.
