Cable strain relief

Cable strain relief is a corrective action for cable defects. It means fixing how cables are held and supported so they are not pulled or stressed at their connection points. It applies to damaged or undersized DC cables, which can lead to overheating, insulation faults, ground faults, lost production and fire risk. It is usually done together with replacing damaged cable runs, correcting cable routing, and shielding exposed wiring from UV light and mechanical damage. After the repair, check that the cable insulation is still intact. One installation manual shows a practical method: where needed, tie the conductors to a strain relief bar with cable ties. That example covers AC conductors in a battery system, not a PV array. The sources list strain relief only as part of a set of repair steps. They give no figures on how well it works by itself.

<!-- review notes

• sentence 1: support check: partial - Passages list 'correct routing and strain relief' as a mitigation for cable defects, but do not define strain relief as fixing how cables are held so they are not pulled or stressed at connection points.
• sentence 3: support check: partial - Mitigation lists replacing damaged runs, correcting routing and strain relief, and UV/mechanical protection together, but 'usually done together' and 'shielding' are paraphrase stretches not explicitly stated.
• sentence 6: support check: partial - Strain relief appears only within a list of mitigation steps and no effectiveness figures are given, but the claim about 'sources' broadly is an absence claim and the Megapack source shows it as a standalone installation practice. -->
