Switching surge guard brands
I had my previous TRC Surge Guard for several years when it finally went. Since it was user friendly and seemed to be very reliable, I purchased another new one (50 amp version) however this time it o...

Having OEM strongly recommend having a pro supervise the job is something I agree with (Massachusetts) "Vagah".
Here is a general question and no it isn't sarcasm...
Is there a rational source for giant pins for connection to the tin plated square aluminum blocks found on many of today's low voltage power electrical components and circuit boards?
Squashing fine wire strands, sucks, period. Let's say a pin for number four AWG cable can be found that will fit an aluminum block....the integrity of such a connection will be infinitely greater than if the screw was put to the fine-stranded wire.
Screw clamped wire MUST BE THNN type with thick strands for this type of clamp to work! Cable that is appropriate inside conduit with sweep bends and pull ell fittings. Any professional who advocates using fine strand wire with a block and screw termination needs to be hung by his reproducers.
I have soldered ends of fine strand wire then laboriously hand-filed a flat spot where the screw fits down onto the wire, with a spiral etched set screw such a termination can and will endure years of service in an environment with vibration. Tin to lead is even nicer to the tin than tin to copper.
But jeezo, who has fifteen or minutes to spare crafting a single leaded and flat-spotted end?
Tighten the scrontch out of a correct cable termination that has electrolytic silicone grease applied to it and it will not overheat and deteriorate -- ever. It is a one shot deal. Before finger-wagging starts clue yourself into jut how many "failure of neutral in a 50 amp service" has occurred. This isn't a bit funny.
But I would like to source reasonably easy to get PINS for this type of termination. Up to one gauge pin size.
