A support assembly, comprising: a support structure; a P-clamp attached to the support structure, the P-clamp including: a clamp body defining an opening; a mounting base structured and arranged to engage the support structure; a connecting section interconnecting the clamp body and the mounting base; wherein the P-Clamp is arranged in an inverted upright position where the mounting base is attached to the support structure underneath the clamp body relative to a direction of gravity, and wherein the P-clamp yields at the connecting section upon an application of a load force to the clamp body equal to or greater than a predetermined applied load force threshold; wherein the P-clamp has a predefined deformation characteristic under a predetermined loading profile where the connecting section bends as the load force applied to the clamp body increases and plastically deforms when the load force reaches the predetermined applied load force threshold; wherein the P-clamp progressively deforms under the predetermined loading profile such that the clamp body is rotated away from the support structure and displaced towards the mounting base when the load force applied to the clamp body reaches the predetermined applied load force threshold; and wherein the support member is a resilient cantilever structure overhanging the clamp body, and includes an outwardly extending portion running transversely to the support structure and a depending portion extending transversely from the outwardly extending portion towards the mounting base, and wherein the depending portion is structured and arranged to apply a force against the clamp body, at least a component of the force being directed to the support structure. a support structure; a P-clamp attached to the support structure, the P-clamp including: a clamp body defining an opening; a mounting base structured and arranged to engage the support structure; a connecting section interconnecting the clamp body and the mounting base; a clamp body defining an opening; a mounting base structured and arranged to engage the support structure; a connecting section interconnecting the clamp body and the mounting base; wherein the P-Clamp is arranged in an inverted upright position where the mounting base is attached to the support structure underneath the clamp body relative to a direction of gravity, and wherein the P-clamp yields at the connecting section upon an application of a load force to the clamp body equal to or greater than a predetermined applied load force threshold; wherein the P-clamp has a predefined deformation characteristic under a predetermined loading profile where the connecting section bends as the load force applied to the clamp body increases and plastically deforms when the load force reaches the predetermined applied load force threshold; wherein the P-clamp progressively deforms under the predetermined loading profile such that the clamp body is rotated away from the support structure and displaced towards the mounting base when the load force applied to the clamp body reaches the predetermined applied load force threshold; and wherein the support member is a resilient cantilever structure overhanging the clamp body, and includes an outwardly extending portion running transversely to the support structure and a depending portion extending transversely from the outwardly extending portion towards the mounting base, and wherein the depending portion is structured and arranged to apply a force against the clamp body, at least a component of the force being directed to the support structure.
