the newest good sockets have screw clamps but cheaper ones still just a screw.. the first thing an electrician is thought is that if putting a single cable in a socket..with no loop in loop out..then you bend the single core back on itself into a small double core state..then when you tighten the screw it tightens evenly on the 2 cores instead of one..if only 1 core is used the screw can cut into the copper and cause a potential weak spot..thus..a potential break point..or..even worse..a saftey concern if high current is drawn by the circuit and inadequate fusing is used! you also have to bend the copper wire the correct way..as the screw always goes in by turning it clockwise..not anti-clockwise
the point is..you can read and study all the information you want..but..unless you actually do it..and keep doing it until you get it right..you will never do it correctly! i can strip the outer core and inner core with just a pliers..no special striping tools required..no scoring of the copper.. after many times doing it..you automatically apply just the right amount of pressure with the pliers..in fact..you do it without even thinking about it.. the odd time..if you are thinking about something else when you should be "working"..then you will nick the copper wire a small bit..but you will know right away..which means..you have to cut the nicked bit off and do again..which is why you ALWAYS leave a spare bit of cable above the ceiling..or behind the cavity..just in case you ever need it.. after all..the goal is to ALWAYS do the job right
i am currently watching PBS America which is showing.. "The most dangerous man in Tudor England" well worth watching..another "link" in the chain to understanding..what a bunch of controlling "bastards" !!
btw..ferrules are only used on stranded copper cores..not on single solid copper cores..as this will not make a good connection.. if looping a cable..the the 2 cores are twisted together..again in a clockwise direction..i have often joined 3 cables in a socket..so you will have 3 cores twisted together..not a problem ! you have to be very careful with any cable termination over 2.5 mm squared..as over this the current gets up to 35 amps depending on load..and higher..so loose connections or damaged cores can overheat..thus causing a fire hazard..any core over 2.5 mm is usually stranded..which means more current carrying capacity..and more cost sockets and switches are the easy part..the fuseboard is the one that catches the handymen
You don't necessarily need to make directional bets to extract money from the market. You can earn a good living betting that a financial instrument will NOT touch a certain price before a certain date, for example.
He can answer... but my guess is that you guys are talking about two different things. But I am sure your original comment relates to the obvious, but doesn't have anything to do with derivatives of the underlying.
