Copper both protects from surface corrosion, and to a degree will help conductivity disproportionately more due to the skin effect. Although that's a lot more prevalent at high frequency. Cheers Flame, Is there a particular reason to prefer the pin crimps over ferules? Fubar

Do the regulations stipulate a proactive changeover of existing CCA during any work then? Would the ferules not act as said load distributor in this instance, or would it need to be substantially more rigid? Fubar

Ahhh, so you could have a good solder joint on the copper plating, but the alu core just eats away. I like rising clamp connections, but the designs (cosmetically) are somewhat limited and I'd rather not replace all the sockets. Would rather have a clean way of either terminating CCA in a...

Re-wiring would be pretty destructive to the otherwise freshly decorated house. Cables, as far as pure conductors go, look alright. Just the termination that's a pain. Not a fan of those crimps. I get why they're used, but at least with a ferrule, you are clamping on the wire itself, albiet...

Power tools... Sleeves... Power tools... Sleeves.... NOPE! Worse than wearing gloves :|

Results of termination tests: Left to right 1) CCA cable, fresh from a strip. 2) Lightly torqued in a screw fitting, note the broken strand. 3) Soldered and torqued (NOT COMPLAINT), improved mechanical response, but still a lot of deformation. 4) Crimped with a ferrule. Improved...

Bits and pieces on wiring

Yup. States Copper Clad Aluminium down the length and is ridiculously soft and light. Huh, did not know that one. What's the reasoning behind the failure? mechanical stress, chemical incompatibility... etc? Fubar

In the process of re-modeling the kitchen and have stripped out all sockets and intermediate cables. I'll re-run the new stuff in 2.5mm T&E, but the existing ring is 4mm copper clad alu. And it sucks. The ring impedances measure fine for the rest of the house, insulation is in good condition...

Managed that not with a tape measure... But with two of these... They were tangled together, so I wrapped the tangled threads around my fingers and sharply jerked them apart Tensile strength of stainless : 860MPa Tensile strength of skin : 20MPa Enough to say that there was a lot...

Actually, yea, quality and delivery were fine. I would recommend as a credit card purchase though just in case (Can reclaim money if they mess up). Fubar

As much as I love pie. I'm not sure I follow.

A lot more energy in a disk than a chainsaw blade. Just not as much input power. You can easily store a kJ of energy in a grind disk. About twice that of a .45 bullet, which is why they kick so hard if they catch. I'm somewhat happy they don't stop instantly as god knows what damage that...

*shudders* angle grinder to the shin would be a bit nasty. I had a workshop bod at uni who used to work in a steel shop. Someone dropped their 9inch grinder once on the blade and just hid it back in the tool cupboard. Next person to use it got a piece of blade through their leg when it...

Welding gloves would be mostly impervious. But then you start to loose the feeling of the tool and the risk of it slipping / cutting the wrong place can increase. I do keep the guards on (half guard for 4", full or half for 9") depending on the job. But yea, got my finger trapped in the...

I'm not a big glove advocate. For one, my history with machine tools taught to never, ever, ever wear gloves as they can get caught. And I carry that through to anything spinny. My finger got a bit chewed up without gloves on. If I had gloves on, they could have got caught, pulled in and my...

It's good to be reminded on occasion just how squishy the human body is. And how the loss of concentration for a fraction of a second can instantly change your life. This one, thankfully, isn't bad. But after 3 hours of grinding a floor, I was tired and the goggles were getting a bit fogged...

Injuries that I've had that should make you think twice.
