Machine Tool Wire Vs Thhn

Machine tool wire or most commonly referred to as mtw is a stranded flexible hook up wire.

Machine tool wire vs thhn.

Although machine tool wire is qualified for many wiring applications it is a simply. As other post indicate it is a poor choice for control panel interior wiring. This high stranding of bare copper gives the wire its superior flexibility compared to that of thhn building wire. Thhn stands for thermoplastic high heat resistant nylon coated.

While both can be used for machine tool appliance and control circuit wiring the difference lies in the fact that tffn is used in applications where the nec designates fixture wire while thhn is not. Thhn thwn mtw is a general purpose insulation system for field wiring. The most popular type of building wire used in construction is thermoplastic high heat resistant nylon coated thhn wire. The uninsulated version is not thhn thwn rated and is used in the creation of windings for power supplies and motors.

The pvc insulation is meant for use in most household appliances. It dress very nicely due to its flexiability. This wire is often found in smaller gauges and sometimes with tinned ends for ease in soldering. Because tffn and thhn wire have different ratings and are available in different gauge sizes there are slight differences in their uses.

Thhn wire is also commonly used in machine tools control circuits and some appliances. Mtw machine tool wire is only allowed for this purpose. Mtw is used for the internal wiring of appliances including refrigeration equipment automatic washers air conditioning equipment control wiring for machine tools and in various other building applications. Mtw wire is used indoors only because it cannot resist water at all.

Typical uses of tw thw electrical wire tracer are in control panels air conditioning equipment refrigeration equipment control wiring of machine tools and automatic washers. Mtw is ul rated for 600 volts. Nylon outer jacket with a polyvinylchloride pvc insulation. Thhn wire can be found in a variety of forms.

Can be solid or stranded depending on the size. The difference between thhn and mtw is the nylon over the pvc insulation on the thhn wire. Depending on the size can be either stranded or solid. The nylon jacket is essential for mechanical protection and protection from abrasion when the wire is fished through conduit.

It is a pvc hookup wire and although machine tool wire is qualified for many wiring applications it is a simply constructed wire that is made up of a highly stranded bare copper conductor. Mtw stands for machine tool wire. Machine tool wire mtw consists of stranded soft annealed copper conductors insulated with polyvinylchloride pvc. Machine wire rated mwr wire often has the dual thhn thwn rating stamped on its nylon or pvc jacket.
