Just kidding of course. Best to keep rectifiers off the tower IMHO

Thanks DanG
http://www.newark.com/multi-contact/69-0012/fuse-0-5a-mc-iv/dp/08R6144  Seems to be as close as I can get. I wonder what the total cost would be. $2+ a fuse isn't bad if the shipping is cheap.

is this for tower-top mounting (at the alternator)? or at the base of the tower?

Anyone found a lower wattage Grid tie Unit, 500 to 1,000.  With some Experience to its workman ship.
Thanks for any reply. I have a small 48 volt 3 phase turbine and 4 x 100 watt panels. total.

Mary B That's not the one, unfortunately. The fuse in my meters looks like a normal glass ceramic fuse. I am using a 250v 500ma fuse for now.

There is discussion in another forum about which multimeters are actually safe and to code. As DanB pointed out, the fuse rating in the booklet is lower than the supposed rating of the device. At 1kv physical separation of components inside to p...

the difference is the flourosulfat (I think that was the chemical) arc quenching sand that is in them.

It kills any attempt of an arc forming

progress!

Holes drilled on the ozone cell and some simple caps bored and drilled n taped for the fitings. Now need to make the Circuit board and finnish the cells anode.

after hunting for some circuite ideas and came accross this gem, the fellow did a great job on making a very simple system with a clean out put, so rather then rebuilding the old cb I'll make a whole new one.

I haven't seen a car's coil like that one in years :-).
Will be an interesting follow.

I have 2 multimeters that I use to indirectly measure 1000v (very low amp) DC power supplies. I cannot find replacement fuses rated 1kv.

What is the real difference between a ceramic glass fuse rated for 250v and the one rated 1000v? Both look the same...
