Common mistakes by MEP team to be avoided in projects
Hello everybody, today I will talk about some common mistakes done by some electrical designers and execution teams while installing the electrical conduits (embedded in the slab or exposed) in projects. 1- the First mistake is: more wires or cables are pulled inside a conduit which is exceeding the accepted fill ratio. As per NEC table 1 in photo no.1, the maximum allowable fill ratio for more than 2 cables inside a conduit is 40%, but sometimes a designer or installer or both of them forget or doesn’t take care about this point, so we will have a lot of wires or cables are pulled inside a conduit and take a space inside the conduit more than the allowable fill ratio. 2- the Second mistake is: Junction boxes are not provided in the routing of electrical exposed EMT conduits, while we have more than four 90-degree bends, because this affecting on cable or wire-pulling inside the conduit.
