Regular cleaning is the foundation of electrical cabinet maintenance. Dust and dirt affect heat dissipation and may cause short circuits; we recommend cleaning the cabinet interior quarterly.
Check that sealing strips and door locks are intact to ensure the protection rating does not degrade due to aging.
Regularly tighten wiring terminals to prevent poor contact or overheating from loosening.
Check that cooling fans and vents are working properly to keep internal temperature within a reasonable range.
We recommend a comprehensive electrical inspection annually, including insulation resistance testing and grounding checks.
