Electric cables and wires always need a robust protection. Manufacturers in the market are providing several different kinds of protective shields, and brass conduit fittings are mostly used by industrial clients. On the basis of usage, suitability, and applicability of conduit fittings, manufacturing companies have vastly separated them into certain categories. Any fitting should meet the specifications set by the NEC (National Electrical Code) as it helps in determining the usability and application of conduit fittings.
What things to keep in mind?
You should be aware that the building codes of one locality vary from the other. It is important to keep the coded specification in your mind to pick the right metal conduit fitting for your new project. It is also required to analyze the uses and benefits of that certain category of conduit and know whether they meet the needs. Evaluation comes next. Weigh and evaluate the differences between the several categories of metal conduits.
Specifications of conduit fittings types
Besides analyzing the local codes, you must be aware of the difference between every conduit design. Once you understand the differences, you can aptly select the fitting for your project. You should know the features, characteristics, advantages and limitations of metal conduit fittings and non-metallic counterparts for better decision making.
Types of conduits available in the market-
- RMC fittings – Rigid type metal conduit fittings are applied in both concealed and exposed applications. These fittings have factory-threading at either ends that is benefitting to the electrical wires.
- Electrical type metallic tubing is galvanized. Due to their design, these conduits function best in situations that are prone to rusting and corrosion. Electrical type metallic tubing such as brass conduit fitting is rust proof and corrosion resistant.
- Flexible type metallic conduits initiate easy handling and installation. While installation, professionals cut the conduit using specific tools. You can use them in both hidden and exposed applications, but avoid installing them at dry locations.
Limitations of using metal conduit fittings –
- RMC fittings are expensive and heavy in weight. You cannot bend them easily and need specific tools for handling.
- EMT fittings are not meant for areas that are prone to material damage
- FMC fittings are not corrosion resistant and so, you cannot use them in wet areas
Brass conduit fittings are best choices to pick. You can get them easily from hardware store dealing in brass fittings and components. Brass material is durable and corrosion resistant and most of the fittings used by industries are made of brass.
