I was looking at 5 7 year old Sharp ND-240QCIBX in a local listing for 95 dollars each. First impression was thats not bad even if they have degraded 10% or so. But now I'm rethinking that. Maybe these are not such a good deal.

The Wisdom of Mr Natural!

At a local level small operators like the guy repairing the battery are mostly just making themselves sick and maybe the neighbours. But battery repair is a very common trade in many cities int he third world. Lots of small shops together can poison the ground water for a whole town. On an...

I work in an industrial facility that exceeds the US EPA lead emissions for a lead works. We are not even in the lead business, its just an OOPS that goes up the chimney... But they got permits to do this. I am hyper sensitive to the pollution from the green revolution because I am a part of...

Leave batteries intact in their cases. Bring to a proper recycler. There is so much lead slipping into the environment that its scary... Lead gas gone, lead paint strictly regulated. But Lead from Electrical equipment is increasingly being lost into the environment. Its bouncing around 1 USD...

Is that Significant?

I am aware of a few industrial process that are using XP computers. They are not connected to any networks, the operating system is very stable and my employer is so cheap if it cost a nickel to poo that would make us throw up... A sister plant up wind of mine is one of the most dangerous...

Jebus Crisis... How do you explain that to people?

Items imported to the EU from China might be subject to duties. You might need to use an import broker to lubricate the right palms. If you live in a place like Rotterdam or close by, you can go directly to the port and collect your items, fill out the paper work and pay any associated costs...

I don't think you have much choice. GE is the last American company I can think of that had a light bulb division and technically that company doesn't exist anymore ( the GE stock ticker actually represents the company remnant that build jet engines ). GE had a hard time giving up the lighting...

You like that butane stove buy a Coleman 500 gasoline stove or 4M... Profane is expensive.... Gasoline is cheap. A completely unmodified 4M will burn Kerosene and diesel with preheat ( latter will cause serious carbon fouling and require a lot more gas gen cleaning )

Run a 4 conductor wire use the Blue and red for DC wiring and the black and white for AC

I never met a man that ran electric that wanted to use Diesel. But most companies unless constrained by emissions and ventilation rules abandoned them years ago. I loved them. I was the last electricians who was qualified a motorman, and switchman be for the last unit was retired. And I think I...

Ya it was a thought of mine too. But it looks like I wont be building anything because of property squabble....

Kubbota or Onan powered? The KUb D905 and D1150 have an aftermarket clockwork starter....

I was going to suggest that as a possibility but that Scotsman beat me to it.

Under extra low voltage rules you may not need to fuse both lead and disconnect both leads. I work at a little high voltages, and larger electric equipment, might be subject to different rules...

First off there is nothing tiny about an onan. That's 40 - 60 cubic inches of flat head fury... Depending on the age your Onan it might be exciter cranked or the last of them had a starter motor.The exciter cranked units needed a lot of amps to get them rolling over because obviously there is...

I see that square D Disconnect you have there. I am not sure its rated for DC at 600 volt There was a rule ( would need to check a current code book ) that said both negative and possessive leads had to be fused or one grounded. Both required a disconnect means of not grounded before...

Never the less the experts consider that extra low voltage ends at 30 volts and thats because there touch potentials they are concerned about. There was time when that was considered the best and safest voltage for a DC lighting systems That's why something like this delco 850 was designed to...

Going over 33 volts means your system falls under a different set of regulations in some places ( maybe not in some or all of the USA ) You may not be able to get insurance unless you pulled a permit and had it inspected. You may run afoul of local electrical authorities with a grid tie system...

Schneider electric. Well I think of all the products made by Square D Modicon and other brands they now own and am well disappointed. I cant speak for the Home inverters but the industrial products some of them make you scratch your head. Connectivity issues and clunky? They make a smart motor...

Ya thats white asbestos, There are different types the white was the best and doctors say the least dangerous to your health. If full of asbestos and PCBs among other things they told me not to worry about. Well I'm worried I wonder if I will be worried long

You might see this in the scrap yard. Those are copper buss bars in an old Westinghouse panel board. The bus is rated at 1200 amp and all those holes are drilled and may even be tapped for 1/4 20 bolts. If you find the bolts with it those are self tapping and will thread the holes in the bus for...

In another thread about bus bar I started down a rabbit hole. So I'm going to talk about junk here. This is all junk leave it alone..... We can zoom in good on this ebay auction stuff. This switch is junk its worthless and its made of asbestos and lead paint. You can see the asbestos fibers in...

I can't zoom in any closer. This is an old Amalgamated electric switch. If you look close all the parts are mounted on that grey cast plastic. Thats actually phenolic... This is important read and process!!!! Back in the day they would make a paste of phenol formaldehyde and white asbestos and...

You guys like buss bar but this is a modern 400 amp splitter and its got some nice mechanical lugs in it with insulators you could repurposed for your battery banks An old one would have three copper buss bars in it. Its not very common to see new buss work like that but its still being made...

If there is a panel shop in your area ( thats shop that build large motor starters MCCs switch gear.... ) they probably have a drum of scrap copper. You might get lucky and they might cell you some scraps. Also ask if they have any scrap copper bolts nuts hardware... Look up the prices at the...

I bet if you go to a scrap yard you can buy some cheap used buss for about 4 bucks a pound. Plain copper is worth more than plated so don;t let them screw you. If its black no issues just clean it with some scotch bright.

HA HA HA.. One of my apprentices made a Boob in a zip lock bag with some left over reentryable compound one time. It did feel fleshy...

A lot of the young electchickens I work with have a love affair with silicon They will glue things on doors with it plug holes ect. Use it for too many things... I really hated it on motor boxes. I knew it was damaging the slip rings and brushes inside and it pissed me off to know end ( still...

Reenterable is like Jello

I have a preference for Urethane over Silicon. Its probably not critical here, but in some electrical equipment Silicon causes problems, the fumes are corrosive and any contamination on brushes or slip rings will cause major problems

Put some gypsum board between the wood and electrical parts to improve that Other wise its a nice looking kart

I have a question for the fusing experts. I stripped out an Exide 300 amp battery charger ( 90 volt 300 amp ) This originally charged Loco batteries. I salvaged A KD molded case switch rated at 400 amps, saved the bridge, fuse holders, metering, and some assorted other bits. I in the past made...
