Faulty AC Adapters Exposing Live Terminals at 230V

AC adapters & chargers are commonplace in every workplace nowadays, whether used for mobile phones or supplying certain IT equipment. So Faulty AC Adapters are beginning to become a problem.

This week, we have again identified a safety issue that can occur with some of these appliances. Most of these items are constructed from two halves of a molded casing which are glued & sometimes screwed together. Occasionally however this fixing can fail leading to the casing coming apart and causing a faulty AC adapters exposing live terminals at 230V potential.

Of the three photographs, the unit laid out in two pieces failed the first time the item was removed from the wall socket. This charger was actually a replacement for another unit that had failed in the same way!

Male connector fitted with exposed terminals

Can you see a problem with this? Would you spot the dangers of exposed terminals?

The plug, the flex and the three-pin connector all look to be in perfect condition don’t they? However, this lead could quite literally be lethal.

It appears that someone has unwittingly, maybe during a momentary lapse of concentration fitted a “male” connector with exposed terminals on the end of a 13-amp plug, now imagine this plugged into a socket outlet with those exposed terminals at the end and suddenly it no longer looks quite so innocent.

A Veriserv engineer found and removed this from a site this week emphasising the need to be extra vigilant for such seemingly innocent and yet very dangerous pieces of “DIY” equipment.

The IET recommend that formal visual inspections be undertaken periodically by a competent person to identify these hazardous items.
