Your Peace of Mind | 2020 NEC Revision

How much is your peace of mind worth to know that you are protecting your home from unseen, dangerous electrical surges in addition to complying with the latest National Electric Code (NEC)? Power surges are an issue because they can damage or destroy plugged-in electrical devices. When too much electricity flows through an appliance at once, the appliance could overheat, break down, or even catch fire.


The NEC is updated every 3 years. The 2020 NEC revision contains a few revolutionary changes for surge protective devices as shown in the video below.



The Mersen® Surge-Trap® Series Surge Protection Device (SPD) safeguards whole house appliances and electronics, including residential air conditioning and furnace units from costly voltage surge events, such as fluctuations in power often generated from inside a home or building, or from an outside source like lightening.


National Fuse Products is a licensed distributor of Mersen® products and highly recommends the Mersen® Surge-Trap® Series SPD for whole house surge protection. For less than $90 for this device, you can now have that peace of mind you are not only protecting your home from a destructive electrical surge event, but also complying with the latest NEC requirements. This device also carries a 3-year warranty. For further information, please visit our product page.


Be Safe Using a Ground Fault Circuit Interrupter

Have you ever considered which is more important – your job or your safety performing the job? You guessed it – your safety is most important. The National Safety Council established June as national safety month. National Fuse Products thought it would be a perfect time to feature one of the more popular circuit interrupters at a sale price of $48.97 (originally $85.70). The Ericson XG2-12-2TT is a portable ground-fault circuit interrupter (GFCI) required by OSHA to be used by all maintenance people in factory environments. For further information or to purchase this item, please visit our Ericson XG2-12-2TT product page.

OSHA Required Insulating Gloves

Insulating gloves are critical PPE (personal protective equipment) for electrical work on or near exposed energized parts. Insulating gloves must be rated for the voltage to which a worker will be exposed (phase to ground or phase to phase) and marked to indicate their rating. OSHA requires that the gloves must be electrically tested at regular intervals of not more than 6 months. If gloves are not used for one year and are still in the box or bag they must to be sent out for testing after one year. The gloves are then date stamped and the clock starts ticking again. If an employee is found to be using out-of-date gloves, OSHA may issue a fine of up to $500 to the company. National Fuse Products carries a variety of Cementex protective equipment which can be found on our Cementex product page.

What does the “T” and “F” stand for when it comes to fuses?
What the T stands for in fuses

Ever wonder what the “T” stands for when it comes to fuses? If you answered “Timed” – you are correct! Timed is the correct term for a “slow blow fuse” which are often called “time-delay fuses.” There is also a double “TT” rating which denotes very slow blow fuses. Alternatively, “F” stands for “Fast” or “fast acting fuses” with the “FF” rating for ultra-rapid fuses such as the one shown here. The ultra-rapid fuses operate at higher temperatures so are ideal to provide circuit protection to semiconductor devices. The fast-acting fuses are ideal to protect less sensitive components.

A Fuse Is Tripped By Heat, Not Current

A fuse is not tripped directly by current but rather the current creates heat, and heat trips the fuse. This is known as the “heating effect of electric current.” The amount of heat produced by the flow of current through a fuse wire depends on the following factors: 1-Material of the wire 2-Thickness of wire 3-Length of wire and 4-Amount of current flow. The heat produced due to the high current quickly melts the fuse wire and breaks the circuit. Thus, the flow of current stops and the damage is avoided. Many companies invest in the use of thermography devices to identify heating issues before an electrical failure occurs.

Fuse vs. Circuit Breaker

Ever wonder who would win if there was a contest between a fuse and a circuit breaker? When everything is considered – purchase price, maintenance cost, foreseeable service life – a fuse proves to be the winner. Fuses also win out in the maintenance department – where circuit breakers must be checked regularly to make sure contacts are operating properly, a fuses stable nature requires no work at all. National Fuse Products is a leading distributor of North American fuses, European fuses and Japanese fuses. If we don’t have the fuse you’re looking for, we’ll get it for you at a very competitive price.
