Conduit boxes come in two different materials here in Nigeria. The metallic and plastic conduit boxes. I have met with Electrical technicians that preferred using the metallic conduit boxes and those that preferred using the plastic conduit boxes. Each one of them had good valid points.

However, at Teknitech Engineering Ltd we would advice you choose using the plastic conduit box over the metallic conduit box. Our reasons are clear:
1. The plastic conduit box is much more rigid compared to the metallic conduit box. The plastic conduit box can resist compression from block weights far more than what the metallic conduit box can resist. This point is only peculiar to Nigeria. Our metallic boxes have become thinner and thinner in thickness compared to those seen all over the world. Manufacturers of our metallic conduit boxes made this so in order to make its price competitive to plastic boxes.

2. Sometimes when installing cables and the technician is not careful, certain portions of the cables can become exposed. This means that the conductors will be touching the conduit box. Metallic conduit boxes being good conductors will become energized and thus possess a high risk of shocking people.
