These are photos of unsafe or badly installed wiring which I come across in the course of my work on an almost daily basis.

Some of it is installed by DIYers, and some of it by so called professionals.

This is a GU10 downlighter. It is connected to phase and earth only, yet it is on and working. The neutral can be seen not connected just to the left of the DL.

The CU just visible in the top of the picture is fed from the incommer by a 4.0mm² twin rubber cable. The only OCPD for this cable is the cutout fuse, which was a BS88 100A fuse

This MEM FCU has had it's fuse holder retaining screw snapped off, and as these FCUs have a spring loaded fuse carrier it has been wedged in place with a matchstick.

This Fluorescent fitting was wall mounted in a factory. It is supplied by 2no. 1.0mm² single red cables. It has no connection to a CPC. The corrosion is due to a leaking roof above.

A 60VA LV lighting transformer which has been sat directly on the lamp it was supplying

This is a proteus CU supplying a portakabin. It had a relatively light load on it.

Down stairs loo, installed under the stairs. No external wall, so fan installed in the floor!

Found this under a floor. A DI had replaced the CU but left the old board casing under the floor to terminate the SWA garage supply into. The armouring was left unearthed.

In a cupboard in a nightclub in Leeds. Also feeds 4 offices and a shop above.

DNO cable accidentally got severed during some building work. Tho DNO attended and repaired it. It does not feed anything in this building. It feeds the shop above.

This is one of my own doing. It is under my desk feeding my computer etc

This is a 6.0mm² feeding a 30A joint box. From here is fed a 7.5kW electric hob, 2.5kW electric oven and a socket above for the cooker hood. No fusing down, and no isolator.

This cutout feeds the house it is in on the top set of tails, and next door on the bottom VIR tails in unearthed steel conduit.

This 1.0mm² t&e cable was found sat directly on the back of a GU10 lamp.

This is a proteus fusebox (Its a wylex copy) The circuit fed a 9.5kW shower on a 6.0mm² t&e cable. The fuse was a 45A rewireable. These boards are designed for a maximum of 30A per outgoing way.

A couple of nasty joint boxes found hidden under floors.

A socket rather close to a bath (The bath was just being stored there on a new build project, but made for a good photo)

This is a TP dist board in a commercial garage. The red bits are some plastic hose linking 3no. SP MCBs asif they were TP breakers. There is also a circuit supplied in 0.75mm² SY flex. It is fed from 32A MCBs

Some less than satisfactory supplementary bonding in a church

A messy switchroom wall

This supply appears to have been converted to PME by non DNO staff, when PME may well not be available

This is a GU10 downlighter notched out of a ceiling joist. Fire waiting to happen.

This is a clock point fed directly from a socket circuit. It is wired in speaker wire, and there is no earth.

I fount this joint on the earth wire of a submains cable

This was done by a former coleage of mine. He was working live and got it so very wrong.

Another bad joint box

A fuse has been reinserted onto a fault

Found this flush mounted fuse box in the back of a kitchen corner cupboard. Not very helpful.

A loose connection in a commercial light fitting.

There had been a short on the ring, so the affected live had been disconnected at eiter end. (The socket and JB both supply a spur)

Found this 240V light in a shower cubicle. It is fed in 1.0mm² cable, direct from the 6.0mm² shower circuit

Earth terminal used as a live connection

What IP rating is that then?

Found this under a floor

Submains supply fed direct from the incommer with an RCD ONLY. No OCPD protecting the supply cable

Not electrical I know, but this is my car after I attempted to park it in a wall one icy February night….

Loads more to follow when I get a bit more time……..
