Question: The contractor installed cable tray covers that are not vendor supplied. They are fabricated in their local shop. To say the least they don’t look like a ‘workmanlike manner’ - plus they have sharp edgesShould this installation be failed ?Enviado desde mi iPhone utilizando Tapatalk
Yes, this installation should be failed. Here's why: Safety
Sharp edges on cable tray covers are a significant safety hazard. They can cause cuts, scrapes, and potentially more serious injuries to anyone working near the cable trays. This violates fundamental safety principles.
Workmanship
As you already noted, if the covers don't look like they were installed in a "workmanlike manner," it's a problem. "Workmanlike manner" generally implies a professional level of quality, neatness, and adherence to industry best practices. Poorly fabricated covers with visible imperfections and sharp edges clearly fail to meet this standard.
Code Compliance (Likely)
While the exact code depends on your location (NEC in the US, etc.), electrical codes generally require installations to be done in a safe and workmanlike manner. The non-vendor supplied, poorly fabricated covers likely violate this general requirement.
Potential for Cable Damage
If the covers are not properly designed or installed, they could potentially damage the cables within the tray over time through abrasion, pressure points, or heat build-up.
Lack of Certification/Testing
Vendor-supplied cable tray covers are typically designed and tested to meet specific standards for load-bearing capacity, fire resistance, and other relevant performance criteria. Shop-fabricated covers lack this assurance.
Here's what you should do
Document the Issues
Take clear photos of the cable tray covers, highlighting the sharp edges, poor fabrication, and any other deficiencies.2.
Formally Reject the Installation
Inform the contractor in writing that the cable tray covers are unacceptable due to the safety hazards, poor workmanship, and potential code violations. Clearly state that they must be replaced with compliant covers.3.
Specify Requirements
Require that replacement covers be from a reputable cable tray manufacturer. Specify that the covers must be installed according to the manufacturer's instructions. Emphasize the need for a safe and workmanlike installation.* Request submittal data, including cut sheets and compliance certifications for the covers.4.
Consider Consultation
If the contractor pushes back, consider consulting with an electrical engineer or inspector to provide further support for your rejection.
In summary, the safety risks and the failure to meet workmanship standards are more than enough reasons to fail this installation. Prioritize safety and compliance by requiring the contractor to replace the covers with proper, vendor-supplied components. Flag for review
