Open a connector catalog and the same C13 plug may appear with several contact finishes: nickel-plated brass, nickel-tin, gold, or tin-plated tabs. These differences are not cosmetic, and the price gap is not arbitrary. Contact plating directly affects corrosion resistance, wear, conductivity, and long-term performance under repeated insertion, heat, humidity, and electrical load. This article […]

Choosing a fuse for a fused IEC inlet involves more than matching the fuse rating to the equipment's normal operating current. The fuse must fit the holder, stay within the inlet's electrical ratings, and respond correctly to both normal inrush current and genuine fault conditions. A fuse rated too close to the normal load may

Heat shrink tubing and cable sleeving are small parts of a wire harness, but they play an important role in protecting the assembly from abrasion, moisture, strain, and movement. They are often selected after the wire, connectors, and routing have already been defined, which can limit the available options and create fit or protection problems

A power cord can look perfectly normal and still have an electrical safety defect hidden beneath the jacket. Thin insulation, a stray copper strand, damage from stripping or crimping, or trapped moisture may not be visible during inspection, but any of them can compromise insulation or protective grounding. That is why visual inspection alone is

Hospital gradeGreen dotNorth AmericaOEM / ODM The green dot on a hospital-grade plug is more than a visual identifier. It indicates that the plug and cord set are designed to meet specific requirements under standards such as UL 817 and UL 498, including provisions related to grounding reliability and durability. That matters in healthcare environments,

Browse the Lanz IEC connector range and you may find two parts from the same family with different current ratings. One IEC 320 C13 plug is rated 10 A at 250 V AC, while a C14 plug connector is rated 15 A at 250 V. Both use flame-retardant nylon housings and nickel-plated brass contacts, and

An IEC connector has to hold firmly enough that the cord does not work loose in normal use, but not so tightly that unplugging it becomes difficult or risks damaging the equipment. IEC 60320-1 addresses both sides of that requirement with minimum and maximum withdrawal-force tests. Request a Quote Minimum and Maximum Withdrawal Force Clause

Two IEC inlets can share the same C14 interface and 10 A rating yet require completely different panel designs. A snap-in inlet locks into a punched cutout with retaining tabs, while a flange-mount version is secured with screws. The electrical interface may be standardized, but the mounting geometry is not. That distinction causes plenty of

When a power cord is pulled, the strain relief should take the load before it reaches the conductors or terminals. If that load is transferred into the termination, the wires can shift, loosen, or fatigue over time. This is why cord sets are tested for pull force and strain relief performance. The test applies a

Put two IEC inlets side by side and they may look nearly identical. Both are rated 10 A at 250 V, both use black molded housings, yet one may cost 20 percent more. The difference often lies in the housing material and in the heat resistance, mechanical strength, flammability rating, and long-term performance that come

Power cord failures often occur where the flexible cable enters the plug or connector. The outside of the cord may still look intact, while repeated bending and pulling have already damaged the conductors or terminations inside. A properly designed strain relief helps reduce this stress by controlling how the cable bends at the connector entry.

When you strip back the jacket on a power cord or inspect a wiring harness, wire color is one of the quickest ways to identify each conductor. Depending on the application and standard, the insulation color can indicate line, neutral, ground, or other circuit functions. For technicians and installers, those colors make wiring easier to
