In another blog about installation errors we are going to talk today about C7 power cord with UL certification. By the way, have you read the previous ones about grounding and fastening clamps?
C7 power cord with UL certification and its function
The function of the power cords is to conduct the energy generated by the modules to the inverter, and from there to the building network. Losses should be minimal as they represent lost money. And the challenge is that the power cords must survive fully for decades – after all, the modules have a 25 or more-year warranty.
Cable protection for C7 cords
Now it is important to remember that we are seeing wires through which direct current, generated by the modules, passes. Unlike circuits in ordinary alternating current wiring. In C7 power cord with UL certification, there is no circuit breaker or other device that trips, cutting off the current.
One hazard leads to another hazard
We don’t get immediate damages from uncovered cable wires at first glance. But the cable will not remain stationary in this position: the wind moves it, and so does the thermal expansion. Moreover, there are chances of tripping and shortages that leads to hazardous outcomes.
Over the 25-year warranty period of the modules, every movement, however small, will have an impact and compromise the cable’s insulation. If your wire is not insulated well; it will affect it performance also due to repeated distortions and you will be at risk of threats.
Use the correct wire for C7 power cord with UL certification as per standard!
It is possible that the handle of wiring would start losing its color; it would lessen the visual appeal also. This shows that it has no protection against ultraviolet rays, which is mandatory for photovoltaic power cords by the ABNT 16612:2017 standard.
You’ve certainly noticed that the other power cords in this photo were also inappropriately placed, passing through a sharp edge. For US American wire gauge (AWG) is set as a standard for wire measurement correct cutting and usages for C7 power cord.
How to protect the wires?
Underneath the modules, the wires must be fixed with clamps. Avoid sharp turns, so as not to stress isolation. Clamps must have UV protection , so do not use white or clear ones, unless the manufacturer guarantees this protection. Some vendors for photovoltaic systems offer clamps made of stronger material.
How to get through the tiles?
All wires of C7 power cord with UL certification exposed to the sun must run in ducts such as conduits, cable trays or corrugated ducts. These also need to be resistant to the sun’s radiation, which prevents the use of conduits. The ducts protect the wires also when passing through the tiles. Avoid infiltration.
How to Detect Insulation Failures in C7 power cord with UL certification?
The inverter continuously checks the resistance between the primary circuit and earth. When it drops below a minimum acceptable value, it turns off and presents an alarm on the display or remote monitoring. The problem usually starts to appear on rainy days, when the water conducts the current between the poles, and disappears as the sun dries the vanishing point.
So be aware of these warnings or generation failures during or shortly after rain episodes. The manual measurement of insulation is done with a megometer or a special device and described in standard NBR 16274, which deals with the commissioning of photovoltaic installations.

How to choose the best electrical supply store?
Through this article, learn how to choose the best electrical supply store for C7 power cord with UL certification. When the time finally comes to build or renovate the property, invariably the time to buy electrical materials will come to light. After all, there isn’t a property that doesn’t need electricity.
Therefore, we can say that the electrical part is what gives life to the environment. For the property to have all its functionalities up to date, it is necessary to choose quality electrical materials, from circuit breakers and sockets, to light bulbs.
Store selection for C7 power cord
we are faced with a natural question: how to choose the best electrical supply store? This is a valid question, as there are numerous options for electrical supply stores on the market. With that in mind C7 power cord with UL certification for , we decided to list some of the best tips to help you choose wisely and with peace of mind.
When there is short circuit in the electrical network; you should know what to do? How to choose the best electrical supply store? The first step in making the right decision is to better understand the history of the electrical supply store
Why you should know about supplier store of C7 power cord?
Learn about the store’s history from where you are buying; C7 power cord with UL certification. This way, it becomes easier to choose a professional company that conveys credibility.is important to know how many years the store has been operating in the market, where it is located, the products it offers and much more. Knowing the history and even the origin of the electrical supply store, the chances of making a mistake in the choice are smaller.
Search for prices for C7 power cord
Researching the prices of electrical materials (C7 power cord with UL certification) is essential when choosing the right store. Therefore, compare the prices of products and move away from stores that work with abusive prices or very cheap. Both extremes are dangerous. Therefore, the tip is to choose cost-effective stores and distributors.
So, there are less chances of choosing wrong. Another great tip is to make budgets. This method is very good for those who buy on a large scale. In addition to having an idea of how much the final value will be, making a budget is a way to get to know the customer service and relationship more deeply.
Choose distributors for C7 power cord with UL certification
Not always the best option to buy electrical supplies are the large electrical supply chains. For those who need a great demand for electrical materials, the cost-effectiveness of choosing a distributor is even greater, since wholesale orders would be exaggeratedly expensive in conventional electrical material stores.
