Do HDMI Cables Need to Be In-Wall Rated?

When shopping for an HDMI cable, you may have noticed that some cables are rated as “in-wall” cables while others are not. But what does this rating mean, and do all HDMI cables need to be in-wall rated?

I recently spent hours researching the best HDMI cable I can use for my pool area speakers and in this blog post, I’ll share with you what I learned about in-wall rated HDMI cables, how long must HDMI cables be, and more.

As a general guide, all HDMI cables run through the walls must be certified and rated as suitable for in-wall installation. So, if your HDM cable is going through the walls or ceiling, It is very important to look for in-wall rated HDMI cables if you are thinking of routing the HDMI cable through your wall. 

This is due to the fact that standard HDMI cables are not permitted to be routed through walls since they are tagged as possible fire hazards.

On the other hand, as compared to ordinary wires, there is no heat loss with in-wall approved cables since they are not exposed to the external environment. As a result, many new construction rules will require you to utilize in-wall rated HDMI cables instead of normal HDMI cables.

But, if you are only passing them through the hole (as opposed to sealing them in), a standard HDMI cable would suffice.

What exactly are wall-rated wires, and why are they important?

The term “in-wall rated cable” refers to cables that have been certified for installation inside walls because they do not generate as much heat when in use. ve. If you’ve been using the cable for a considerable length of time to transmit data, you’ll notice that it may become rather hot.

Cables that disperse heat and must be routed beneath the drywall are required to be in-wall rated by the vast majority of building regulations, and HDMI cables are no exception. Even when subjected to heavy usage, in-wall rated connections do not generate as much heat.

Due to its insulation, the wire does not dissipate heat as it moves through the cable but rather moves the heat toward its destination. Heat-generating equipment, such as a gaming pc, can readily dissipate the generated heat.

When should wall-rated HDMI cables be used (and when should they not)?

It is important to examine two factors when considering whether or not you require an HDMI cable that is certified for in-wall installation.

In the case of the concrete wall, this refers to the substance of the wall that you are sending your cables into.

Most homes are composed of drywall, therefore you’ll need to find out where you will be routing your cable before proceeding. Alternatively, you may make a hole in the wall or send the cable up through the roof.

The materials that may be used to create ceilings include drywall and plaster. When it comes to plaster ceilings, the situation may not be quite as bad. However, the dangers associated with using in-wall rated wires for plasterboard are not very high.

Why should you choose HDMI cables that are rated for in-wall installation?

The danger of fire hazards is minimized when using in-wall rated HDMI cables, which are categorized as low-voltage cables. Nevertheless, there is still a chance of a catastrophe. Due to the obvious fibers that surround HDMI cables, they tend to generate a cloud of smoke.

More to the point, if there isn’t a way for the heat to exit, the temperatures of the conduit will ultimately increase, melting the wire. If this occurs in rare instances, it may result in tiny flames that will most probably expand through a length of wire, igniting the rubberized coating outside till it hits anything combustible.

Concrete walls are often considered to be safer, however, the melted wire may still adhere to the surfaces and create a stinky, dark remnant inside the wall. Smoke may be transferred to other sections of the home via the plenum spaces, causing it to harm more than a single room at the same.

Fumes from burning rubber and HDMI fibers might be dangerous to your body since they contain poisonous substances.

Conclusion

Several countries, particularly those with large distances between buildings, mandate the use of in-wall rated cables. Although an HDMI cable, of all items, might not appear to be capable of igniting a fire, you would be amazed how even the tiniest details may result in far greater and more expensive problems down the road.

Aside from being less expensive than standard wires, in-wall rated cables may make a significant impact on the overall performance of a structure. Make the appropriate choices to ensure your own safety as well as the safety of your household and staff.
