An A-shaped fan motor mounting bracket including an arrangement for securing a motor lead protective sheath, such as a flexible metal conduit through which electrical leads for the motor pass, so as to minimize flexing of the leads between the motor and the sheath. In a preferred form, the sheath securing arrangement includes a U-shaped strap having opposed free ends adapted for attachment to the bracket closely adjacent motor so as to encircle and grip the sheath between the strap and bracket. The strap may include a ridge within the concave portion thereof for engaging a corresponding trough in the surface of the flexible metal conduit and the bracket portion to which the strap is attached may be inclined obliquely to the motor rotor axis of rotation for better alignment with the leads which extend obliquely from a strain relief grommet. In an alternate form the flexible metal conduit has a generally helical ridge and trough surface pattern and the bracket is provided with a non-circular opening into which the sheath may be threaded to secure the sheath directly to the bracket.
