Is the cable inside a socket outlet / power strip attached firmly?

Click For Summary

Discussion Overview

The discussion revolves around the durability and safety of the internal wiring and connections within power strips and socket outlets, particularly after experiencing impacts from falling. Participants explore concerns about potential damage to electrical appliances and the overall quality of such devices.

Discussion Character

  • Debate/contested
  • Technical explanation
  • Exploratory

Main Points Raised

  • Some participants express concern about whether the internal wiring of power strips is designed to be tough or fragile, especially after impacts.
  • There is a suggestion that the quality of power strips can vary significantly, with some being poorly constructed, as noted by experiences with low-cost products.
  • One participant mentions the potential for internal components to be compromised if the power strip has transient protection, depending on how they are mounted.
  • Another participant shares a personal experience of inspecting a low-quality extension cord, highlighting poor construction and safety concerns.
  • Some participants propose that without a background in electronics, it might be safer to replace the power strip rather than risk using a potentially damaged one.

Areas of Agreement / Disagreement

Participants generally agree that the quality of power strips can vary and that impacts may affect their safety, but there is no consensus on the specific durability of the internal components or the best course of action after such an incident.

Contextual Notes

Participants mention varying experiences with power strips and extension cords, indicating that quality and safety may depend on the manufacturer and design. There are unresolved questions about the specific risks associated with using a power strip that has fallen.

I have a power strip that has fallen from height accidentally for a couple of times, there is no observable crack or damage, however, could this lead to bad contacts or anything bad to the
electrical/electronic appliance? I'm thinking if the power cable inside is usually well attached

It's probably fine but there's really no way to tell without opening it up or using it.

I'd like to know, if wires and connections inside electric socket of power strip are tough or fragile by design?

The quality of such devices vary widely from very good to very bad. I once examined an extension cord purchased in the dollar store. I was shocked (figuratively) by what I found. I'll never buy stuff like that in the dollar store again.
 
Agree with anorlunda. There was a flap a few years ago about cheap power cords (or was it extension cords) shipped from China that were spontaneously shorting and bursting into flames.

Yes. :wink:

Does it have internal transient protection? If so, depending on how the components are mounted, they could have broken off or otherwise been compromised. Since you probably are not plugging a computer into this power strip that keeps falling from significant height, that may not matter.

That depends, as others have said. I myself would open it up for a good inspection, but I'm an EE with a fair amount of AC mains experience. What is your background in electronics and AC Mains safety stuff? If no background, I'd just buy a new one and fix the setup where it keeps falling... :wink:

How bad was it? Overheated?

I don't think it is a cheap one, but not a decent one though. It fell off from the desk by accident when it was connected to anything. I think this kind of things are not too fragile, but wish to know if it would cause problems to the appliance if used to power them. This is a trade-off between cost and risk so I am asking this question to help making estimate

I cut open the lamp cord wire. I found an inner "tube" in the insulation. The tube was filled with loose strands of wire, each about 1 cm long, not braided or twisted or systematically placed --- just random. It looked to me like copper sweepings from a factory floor.

I could not begin to think how to calculate the standard deviation of the ampacity of that cord.
