In the present paper, we strengthen the assertion of the Wiegold conjecture for nilpotent Lie algebras over an infinite field by proving that if there exists a subset of a nilpotent Lie algebra $\mathfrak{g}$ consisting of elements of breadth not exceeding $n$ and satisfying some additional conditions, then the dimension of the commutator subalgebra $\mathfrak{g'}$ of $\mathfrak{g}$ does not exceed $n(n+1)/2$.
Keywords: nilpotent Lie algebras, finite $p$-groups, Wiegold conjecture, iterated constructions.
