And if you really believe what you have written joe-90 then you are a self deluding "muppet".
Not bad for a first post - but better off using your usual log-in eh?
Anybod recognize this Black and Decker Professional drill?

may i ask have you had the drill on a PAT Tester?
im not disputing that the drill can be repaired and its a workhorse i would imagine, i collect vintage tools inc B&D
Just wondering what the Earth Leakage would be on a 25/6 year old vintage drill! would make an interesting experiment
Earth Leakage Before Repair
Earth Leakage After Repair
Good Luck on Repairing it!

Drill is Dbl ins. So EL n/a.
Have you tested some of your own vintage drills?
Interesting you have collection of old B&D drills. If you have one of these in a suitable condition, I might buy it from you (at the right price), as a spare, or for spares.

Erm no. You still check earth leakage to all metalwork even if the appliance is calssed as double insulated.
yep all my vin stuff is tested the missus has recently become PAT qualfied and bought her a PAT tester and she went beserk on it all!
even if a drill is DBL INS it still has to placed under an earth leakage test!
done one the other nite, rewired it as the flex was looking batterd and it failed e/l test as it was leaking 2a
so a nice shiny red sticker was placed on it and it was placed back in its home! i dnt use any of my vintage stuff its purly for collection purposes! i will however keep eyes peeled for one sim to yours!

That's very interesting.
How is that done on a double insulated appliance without an earth lead? I'm not an expert you understand, so please explain.
The PAT tester has an earth lead which you connect to any conductive parts to check there is no electricity leaking to them.
If you don't have a PAT tester, just carry out an insulation test between all live conductors and any conductive parts.

Don't forget when you do the earth leakage test to pull the trigger on the drill either.
The Law/regs that catch you on that is the Electricity at Work 1989
Where you will fall foul is with Site management.
It's their way or the highway.
What does any of this have to do with the recognition of my Drill? The model number of which I know now anyway.
That was the title/point of this thread. I have no doubt that somewhere on this forum the discussion of electrical testing and regulations are covered fully. Perhaps somebody could provide the link. I can't be bothered to search.
Anyway----- .
Yes. There is a potential earth leakage current path, --- the operator or other person or object, ---- whilst in contact with exposed (if any) metal parts of the appliance in question, -- and "earth". Hence, as described by RF lighting an insulation resistance test will establish if such a path is possible and or significant. A high enough insulation test reading, to all intents and purposes, negates such a path, and consequent shock hazard. I'll leave you to research the minimum acceptable reading. I know it, but think it will benefit those who dont, to look it up for themselves.
The classic "megger" IR test will suffice to prove or disprove the possibility of a path to earth. The introduction of an earth path (for earth leakage current) via test equipment, is not compulsory for class 2 equipment --- as far as I am aware. If it is compulsory, show me the law, I will comply and stand corrected.
Either way, it has not been established that my drill is a "shock hazard". Has it?
That assertion is what started all this nonsense.
If when I am on site, some pat tester wishes to test my tool, she or he is very welcome to do so.
Meanwhile.
As regards site managers, that is a matter of policy not law. Yes some sites do exclude 230volts, but not all. So what?

I shouldn't have abbreviated obviously. n/a was my lazy short hand for not available on a double insulated appliance, because there is no earth lead.

So please quote from the Act, the line that forbids 230v on site, and from more recent and current legislation or regulations that show the same.

The Minimun Requirement for a Class 2 Appliance (Double Insulated) Insulation Resistance - 2MOhms as stated in the Code of Practice for In Service Inspection & Testing of Electrical Equipment
When Testing IR on a class 2 Appliance the test probe should be connected to any exposed metal parte i.e metal gearbox or suspect joints in the enclosure where conductive material may of accumulated this may require multiple testing.
110v on construction sites comes from
Regulation 6 Adverse or Hazardous Environments in the Electricity at Works Regulations 1989:
Regulation 704.410.3 NOTE 1 : The Reduced low voltage system is strongly preferred for the supply to Portable Hand Lamps for General use, and portable hand tools & local lighting upto a maximum of 2kW

So, EL test on dbl insulated not compulsory.
Strongly preferred is not law. Also, it would be interesting to know exactly which edition (date, version, publisher) of the 1989 electricity at work act, you are "quoting" From. A web link/reference would be useful.
