When I started Navy Radioman school (in '63), I could copy 25 wpm with a pencil, but I couldn't type that fast! We had to type everything, so I spent all my code classes running the tapes for the other guys and practicing getting what I heard down on paper with a typewriter. There were five or six of us in Code Control all the time - all of us hams; all of us non-typists.
So if you NEED to copy things verbatim, you could use your computer keyboard, or an old typewriter (which my grandsons call "a keyboard with a built-in printer!!)

Judging from your call sign, the USA/NEMA standards probably don't mean any more than FCC regulations in your case ;-).
Ask the electrician; he can show you what the Canadian electrical code and whatever Provincial code requires. He will most likely be able to provide the correct mating plug for the receptacle he installs.
Have fun!

Speaking of heliographs, here's a poem by Rudyard Kipling, called "A Code of Morals". Note that the General and all of his staff could read the message...
NOW Jones had left his new-wed bride to keep his house in order, And hied away to the Hurrum Hills above the Afghan border, To sit on a rock with a heliograph; but ere he left he taught His wife the working of the Code that sets the miles at naught.
And Love had made him very sage, as Nature made her fair; So Cupid and Apollo linked, per heliograph, the pair. At dawn, across the Hurrum Hills, he flashed her counsel wise— At e’en, the dying sunset bore her husband’s homilies.
He warned her ’gainst seductive youths in scarlet clad and gold, As much as ’gainst the blandishments paternal of the old; But kept his gravest warnings for (hereby the ditty hangs) That snowy-haired Lothario, Lieutenant-General Bangs.
’Twas General Bangs, with Aide and Staff, who tittupped on the way, When they beheld a heliograph tempestuously at play. They thought of Border risings, and of stations sacked and burnt— So stopped to take the message down—and this is what they learnt—
“Dash dot dot, dot, dot dash, dot dash dot”? The General swore. “Was ever General Officer addressed as ‘dear’ before? “‘My Love,’ i’ faith! ‘My Duck,’ Gadzooks! ‘My darling popsy-wop!’ “Spirit of great Lord Wolseley, who is on that mountaintop?”
The artless Aide-de-camp was mute; the gilded Staff were still, As, dumb with pent-up mirth, they booked that message from the hill; For clear as summer lightning-flare, the husband’s warning ran:— “Don’t dance or ride with General Bangs—a most immoral man.”
[At dawn, across the Hurrum Hills, he flashed her counsel wise— But, howsoever Love be blind, the world at large hath eyes.] With damnatory dot and dash he heliographed his wife Some interesting details of the General’s private life.
The artless Aide-de-camp was mute, the shining Staff were still, And red and ever redder grew the General’s shaven gill. And this is what he said at last (his feelings matter not):— “I think we've tapped a private line. Hi! Threes about there! Trot!”
All honour unto Bangs, for ne’er did Jones thereafter know By word or act official who read off that helio. But the tale is on the Frontier, and from Michni to Mooltan They know the worthy General as “that most immoral man.”

Technically (and poetically), it's "iambic" only if the dit comes first. If the dah comes first, it's "trochaic".

Don - did you mean you wouldn't try it with RG-58?
I wouldn't try anything over about 300 watts with RG-58. And most of the "RG-8" available today is junk. Since there's no longer a military specification for RG-8, any manufacturer can call his product "RG-8", regardless of its characteristics. Same thing with RG-8X. It's a tad larger in O.D. than RG-58, but there's no real industry standard for it, AFAIK, except for diameter and Zo.
You'd be better off with RG-213.

As usual, Steve is right on, both with the likely description of the shunt, and the likely condition of the meter.
If you have to replace the meter, find out the precise resistance value of the coil (out to at least 3 decimal places) and the full-scale current it requires. We can do basic Ohm's Law calculations to find out what the shunt resistance should be, and then hit the books to find out how much copper wire of what size and length we'll need to make a precision shunt just for that meter.
