A receptor assembly (1; 5) for a lightning protection system for a wind turbine blade (2) is disclosed, comprising electrically conducting current carriers (6; 19) and mounting bolts (9) and/or threaded rods (20), wherein each of the current carriers is a metallic part arranged and dimensioned to surround at least a part of a mounting bolt or a threaded rod without being in electrical contact with the mounting bolt or threaded rod, at least a part of the external surface at one end of each current carrier is arranged to be a contact surface (10) for mechanical and electrical contact to a receptor base (3; 16) in such a way that, in the case of a lightning impact on the receptor, the lightning current passes through the one or more current carriers rather than through the one or more mounting bolts and/or threaded rods on its way through the receptor.
