HCM73TSD – SQUARE D I LINE TRIM/COVER 4PC DOOR 73 H

The SQDHCM73TSD is engineered for the Square D I-Line panelboard family, which is commonly used in commercial and industrial settings. However, I-Line enclosures come in varying widths and depths, so fitment depends on your specific panelboard configuration. Send us your panelboard model number and we'll confirm compatibility before you order.

Yes — the SQDHCM73TSD is an ideal replacement for worn, damaged, or missing door trim on 73-inch Square D I-Line enclosures. Because trim and cover assemblies are often discontinued or hard to source, Northern Breaker Group specialises in locating these exact components. Contact our team and we'll verify it matches your existing enclosure before shipping.

While replacing a trim cover is generally considered low-risk compared to breaker work, Canadian electrical codes (CEC) and provincial requirements may still apply depending on the scope of work and jurisdiction. In most commercial settings, any work on or near energised panelboards should be performed by — or under the supervision of — a licensed electrician. We recommend checking with your local authority having jurisdiction (AHJ) to confirm requirements in your province.
