Be very careful out there,it might hurt

[cliffed]

Had to fix a trailing swa,with 2g socket on the end of it.
Maintenance sparky checked it,peculiar voltage,40v.
I checked it with my volt meter ,sure enough 40v.
Plug my plug tester in,dead.
Checked the zs & v on my test kit,dead.
Checked with mains continuity tester dead.
Cut it with hacksaw,bang.
Radial serving a number of sockets,no Rcd,16 amp mcb,1.5mm 3 core.
Thinking,the sheath of the live not contacting terminal on socket.
Never take anything for granted.

o well, you learn some thing new every day .

 

[cliffed]

Indeed you do

 

[buzzlightyear]

Indeed you do

yes Stanley.

I think the learning point is to first identify the circuit and its point of isolation and then isolate it before doing proving dead tests.

I would want to know why various tests did not prove live.
Edit: you had to fix it, what was the reported problem in the first place?

 

[buzzlightyear]

Thats what i call bang test!
or was it f##t i will go for it.

Was asked to fix swa & power point,the tests proved it was dead.
Given the information I had,I did all tests.
Lesson learned,ie:ID first,isolate,then proceed.

Some maintenance guy..... doesn't even think of isolation for starters.... that's before your embarrassment.

 

[cliffed]

Yea,another for the book of life.

I hope you had a spare blade in the van for your hacksaw!

 

[plugsandsparks]

Yep, would have been straight forward to find the breaker first as you will have to find it eventually anyway to turn it back on. Would have solved your 40V as well

I store mine in the frame of my Sandvik 225 ;o))))

@SWD Now you're showing off!

Yeh I was getting a shock working above suspended ceiling between the metal grid of the ceiling and the earth of the lighting I was installing of 120v. Most mysterious. Later external lights were wowing and fluttering (17 of them) tested the voltages at the switch end got 200 volts on earth I think and went to work on that fault. Found a neutral on one of the lights junctions was connected to Earth fixed, and no voltage between grid and earth now. But as I result I have added to the safe isolation and teach anyone (younger people who do work for me for experience) to test between metal parts and earth. Who would have expected it though. You just cannot be too careful.
