How to choose a heavy duty power strip?

Why need heavy duty power strip?

I'm sure everyone is familiar with power strips, which are usually hidden under a table or on the back of a sofa. But in a workshop or some place where you need to connect sophisticated appliances, an ordinary power strip may not help you much. You need a more robust power strip with thicker wires and surge protection than a flimsy household power strip. It's not just because it looks good (although a heavy-duty power strip will impress you more) it does protect your appliances from surge damage, and the thicker wire represents a greater amperage. Of course, the rugged appearance will save you money in some harsh environments. You don't want to see a bare circuit board, do you?


How do we choose the right heavy-duty power strip?

First of all, it doesn't matter how many joules, how many amps and how great the surge protection is that the seller brags about the power strip. Don't be fooled by the flashy parameters. I don't mean that parameters are not helpful when shopping for a heavy-duty power strip, but there is no doubt that having a certified power strip is a must for competing in the marketplace. Without it, perhaps the power strip you buy will be an untimely bomb. This is not an alarmist statement, according to incomplete statistics: 30% of fires are caused by failed power strips! So by all means, look at the product packaging and itself to see if it carries the required local certification mark.


Next, determine what you are using the power strip for.
Does it provide the right number of outlets for your needs?
Is the type of device to be connected an ordinary household appliance, or a high-powered electronic device?
What should the cord length of the power strip be?
It's definitely cost-effective to spend some time understanding this. Take your spirit of reading the terms of the insurance and understand the power strip this is definitely worth more than the insurance.

Parameters of heavy duty power strips

Typically, we see some of this data on the title when we order a power strip.

Joule: the maximum value of energy that the power strip can absorb. A higher Joule value indicates a higher level of surge protection and a longer outlet life. This is typically 1000+.

Current: Most wall outlets in your home (excluding air conditioning outlets in high places) can withstand a current of 15A (amps), so most extension cords are rated at 15A, but there are still some extension cords that are rated at less than 15A. It is recommended to choose an extension cable with a rated current of 15A (amps).

FT: The length of the wire of the power strip, normal power strips are 6-8 feet in length. Heavy duty power strips are 15 feet in length. Even longer.

Wire width: This is usually overlooked. Theoretically the thickness of the wire determines the amount of current that can pass through it, for example CRST's heavy duty power strips are made with (SJT 14AWG/3C) wire, and thicker wire can also better protect the wires inside.


Through the above, I think you should have an understanding of the heavy-duty power strip. In a word, it is a power strip with better material, thicker wire and stronger parameters. And there are some features that come with the surge protector. It can withstand more equipment access and higher power electronic devices (still have to calculate the total power to avoid causing a short circuit) If you have more questions about the heavy duty power strip, please feel free to contact us at
