Discuss The big difference in the electric terminology and installation regulations and practice in each country! in the Industrial Electricians' Talk area at ElectriciansForums.net
In South Africa, our job description was Master Installation Electrician, being able to install, maintain and certify explosive and inflammable installations.I believe in the US an apprentice becomes a journeyman when he qualifies, then becomes a master electrician once he has enough experience. I think the master electrician is similar to the JIB approved electrician grade.
I believe this mirrors the way trade apprenticeships worked in this country hundreds of years ago.
She looked great in the classroom too with her leathers, boots and little whipI preferred to be caned on the bum by Miss McSpanker.
Polyphase is also an US term for Split Phase Ie 2 phases that’s what I was referring to.
I was 15th/16th Edition always referred it as “Live” things change.
Certainly I would refer to 110-0-110 style of supplies as "centre-tapped" and not polyphase - that (to me at least) implies phase angles other than 0/180 deg that you can get from a single phase supply & transformer.There is still obsolete 2 phase power being used in some areas of the US, Philadelphia is one city where it still exists, I have never seen it though. Polyphase refers to either 2 or 3 phase, it would not refer to what you call "split phase" but is considered single phase.
In London, black cab drivers are "Journeymen" if they don't own their cab... if they do own it, they're "Mushers"... no idea where any of that comes from.I still want to know what a master electrician is compared to a journeyman electrician...
can you be a master journeyman....
and what the heck is a pony panel
That is another thing, when we hear "black cab driver" in the UK we know it is a driver of a black cab (hackney carriage)!In London, black cab drivers are "Journeymen" if they don't own their cab... if they do own it, they're "Mushers"... no idea where any of that comes from.

Dave in the US you have to have 14,800 primary hours which means being superintendent on jobs then you have to take the masters test. We have guys and girls that can get low voltage license which is under 24vac,swimming pool license, limited license, intermediate license, and of course the Masters licenseI believe in the US an apprentice becomes a journeyman when he qualifies, then becomes a master electrician once he has enough experience.

Not any more, thank God! But you will occasionally see porcelain versions of the wire nuts in stuff that dates from the 60s or beforeWe don't use those turn things for connecting wires - we use connector block or Wagos
Marcus I don’t mean no harm but I have no idea what you are saying. If you are talking about lock out tag out a person could lose their job if they don’t follow the correct procedures.In large scale events, In the UK and EU we use a connector called power lock for our temporary installation supplies rated at 400A and 600A (single pole (5 connectors for 3 phase))
Having worked a lot in America you guys use cam lock connectors which like power lock are single pole and rated at 400A
I struggle to understand why they are still allowed & used as they have the potential to be very dangerous: For these reasons:
- Non-locking
- male to male adaptors
- T adaptors
- Any colour can be plugged into any other colour
- Very large exposed conductors easily touched when unplugged
Powerlock is: locking, will only allow phase to phase or earth to earth connections etc, and has no exposed conductors
I have even seen on TV shoots in the US where camlock is used on a public street and tee adaptors are used as joiners so the side outlet is not used leaving a live exposed conductor on a public pavement.
Although this isn’t a difference in domestic it still might be of interest,

No the "cam lock" is the make of connector.Marcus I don’t mean no harm but I have no idea what you are saying. If you are talking about lock out tag out a person could lose their job if they don’t follow the correct procedures.
