It was oblique so it gained distance as it went uop. I always thought mains leccy went up from the floor, this came down from the ceiling.

if you imagine any socket, lightswitch, etc from the centre of that fitting horizontal or vertical you have to assume that within 150mm 6" there can be a cable

if its outside that its not really your fault

if I am not sure I have a little tap with a hammer and cold chisel before drilling,see if it find the cap it

Chemicals mixed together for weedkilling is industry standard. Any agronomist will reccommend it to farmers for certain infestations. If you have docks and ragwort, you need two diffferent things which work without killing the grass.
dissapointed in you. For hitting the elec. I thought you were mr health and safety

Not really my fault DDD. As LLL states 150, this was way past that and not ducted about 20 ml under plaster. Plus as stated it went diagonal. Thank you....next please :p

The RHS have an interesting page on their web-site about JKW.

It very much seems a plant to dispose of properly and completely as it can regrow from small bits.

DDD is it advisable to mix different chemicals together? I assume it is tried, tested and no explosions? Lol. Short story long.....I cut it down, treated it as said. Tried burning it but a bit wet so cut it up smaller. By now I'm stinking of it and smoke, went indoors to put up a shelf and an elec' cable running at an angle to the main....fecking bang. Lucky me no shock, god knows why. Blew the boiler etc so no hot water. Washed best I could and on train this morning could still smell it all. Bloody lanlord trying to blame me. From gang box rising a metre it is running 6 inches out. Scary.

The only cable that is allowed to run out of vertical or horizontal is the cooker one that has to be exactly 45% from the cooker to the cooker isolation switch for fire reasons

my one was a mains cable 1600 high from the ground but running down laterally from the ceiling to the socket. so it was wrong times to because ( i think ) mains runs up from the floor and lighting runs down from the ceiling.

depends on the age of the house
generally up stairs sockets come up from the floor lights switches come down
down stairs it can be either depending on the ring

Er, no. Absolutely not.

17th Edition electrical regs:

522.6.6
A cable concealed in a wall or partition at a depth of less than 50 mm from a surface of the wall or partition shall: [part of the regulation only]
(v) be installed in a zone within 150 mm from the top of the wall or partition or within 150 mm of an angle formed by two adjoining walls or partitions. Where the cable is connected to a point, accessory or switchgear on any surface of the wall or partition, the cable may be installed in a zone either horizontally or vertically, to the point, accessory or switchgear.

It is possible that a cable runs horizontally from, say, a socket, up to the angle (corner) where it may then go up or down. There may be another cable or cables going off in other directions, also as per the regulations.

Of course the quickest way to find that a cable is less than 50mm from the surface is to drill a hole through it! Not best practise!

I always thought that the "within 150mm of an angle" part was right where you might put a shelf bracket.
