You must totally enclose conductors and their connection external to the control panel enclosure in suitable raceways or enclosures. Unless used for flexible connections involving small or infrequent movements, or connections to normally stationary motors, limit switches and other externally mounted devices, fittings used with raceways or multiconductor cables must be liquidtight.

Transformers may be fitted with turret tags suitable for soldering and printed circuit board assemblies may have solder pins.

In the case of a wire connection, it needs to be a very good conductor. Good conductors include most metals. The most common conductor used in wire is copper, although you may come across others such as aluminium. An insulator on the other hand is a material which does not allow an electric current to flow. Rubber and most plastics are insulators.

When constructing junction boxes and pull boxes, you must be careful to exclude materials such as dust, flyings, oil and coolant. After you complete all wiring operations, you must seal all unused knockouts or openings.

However, an exception allows you to install a splice in leads attached to electrical equipment, such as motors and solenoids.
