Arlec "Do not use Megger"

[DyFamCont]

I've just been to a job to replace a burned out switch where the customer supplied his own Arlec dimmer switch. During a dull moment, I read the Notes for the installer which included: "Do not use a "megger" to test the circuit in which the light dimmer is connected". Has anyone come across this before? It seems very strange to specify a restriction by brand and not function.

Does that mean I'm good to shove 1000v through it, so long as I use a Kewtech? /s

I was also surprised at how poorly made this thing was. Apparently it wasn't an Amazon special!

Seen this before and it is poor wording but we hear it all the time on site the term Megger instead of insulation resistance.

I've seen it plenty of times on older equipment.

I think the use of 'megger' to refer to insulation resistance testing is becoming less common than it used to be.
There was a time when the 'megger' was one model of tester from a manufacturer and was the most common (if not the only one commonly available to the average electrician) so it made more sense as a term years ago.

Problem solved….
I hope you got the ‘hoover’ out before you left

Megger is a universal term for insulation resistance, I'm pretty sure I've even seen the term used sometimes in the Boeing Aircraft Maintenance Manual

Am I going to have to start a whole new post about what a "hoover" is? Sounds like something a plumber would use...

Aico use the term Megger on their CU stickers
