Use a kettle or fan heater.

Use a kettle.

I like that.........another good reason/excuse found for having a brew.....

I was thinking that but didn’t want a search party mob with pitchforks and torches hunting us

Using a kettle encourages you to do the test quickly…. It’ll boil and cut off within 5 minutes.

TJ Anderson is correct especially if its commercial environment. RAMS protect the client
in exceptional circumstances for live working, i would get written instruction from client as evidence, let them assess and manage the risk
you may also need special PPE
if the circuit earth is not identified, will you certify the work?
days of working live on busbars are gone

and always test for live using the back of your hand/fingers.

It's stupid, I know (in the hopefully unneccesary sense), but I always as a sub-conscious 'drilled into me as a nipper' kind of thing, always do tap the back of the finger onto ANY metal enclosure or panel that I have to engage with.

Indeed, touch before you grip, just in case you can never un-grip!

Also old-timers working on valve gear would try and keep one hand in pocket so any shock would be largely confined to a hand. Going to hurt, and possible made worse by cutting the back of your hand whipping it out against any metalwork, but less chance of fibrillation death.

It's also because a burn injury will heal faster on the back of your hand than the palm. I also was taught (and still do!) to work one handed in some situations - and the number of times I've opened up a panel and it all comes tumbling out where there's no dressage and too much untidy slack......

back to the OP - again, not 100% guaranteed - but if you think you've narrowed it down with a clamp meter, see if you can get the live/s in as well as the neutral - theoretically should be solid zero under a full load (unless there's a earth fault).
