Dude thats a bummer about your home burning down. I cant imagine that feeling. We had a big bush fire go through in my state and wipe out a few houses. I remember it because I was working away from home and I jumped in the work car in the morning with my work mate who was distraught. He was watching his house burn down on the nightly news. He recognized his roof from an aerial shot. A fireman was bashing on the door and his wife answered. He said "grab your kids, and go NOW NOW NOW!" she yelled at them to grab their shoes and he said there was no time. As a result, that day all he had was the clothes he was wearing and his family with their clothes minus 3 sets of shoes.
Yes I forgot you you guys were that much different to us!
In my country;
Red = Active
Black = Neutral
Green+Yellow (old standard all green, some still around) = Earth (ground)
I believe in your place white is active? I cant remember.
We still use Breakers here too. But also RCD's. Sometimes you get them in the same package which is known as a combo breaker. I am not sure if you call them the same things over there, or if your quick disconnects are our RCD's?
As you know, Breakers trip when the current goes above their rated trip point for too long a time. I believe your breakers come in different sizes to ours as well as your wire is refered to in 'gauge' where ours is refered to by cross sectional area. So as you know, if you have a wire of a certain gauge it can theoretically only carry so much current. Therefor you select a breaker that will trip out before the wire burns out. Thats how we do it in upside down world anyway. Our standard for power points is 2.5mm squared. Now this can handle something like 25Amp in theory but all the power points are rated at 10Amp (usually). So most houses have a 16Amp breaker for power points. Some people will whack in a 20Amp.
Along with this, they also put in an RCD. The active will go in the top of 16Amp breaker, then come out and go into the top of the RCD. Out of the RCD and out to the field. The Neutral will return to the bottom of the RCD, Come out the top and through to the main neutral. The RCD itself now has the active coming in and out as well as the neutral coming in and out.
As you know, the amps in a circuit is the only thing that is the same at all points. (ignoring places the circuit splits and runs parallel, but the sum of those should be the same). So if you have 8A running through your 16A breaker, and through the RCD you should have 8A coming back to the neutral to the RCD and back to the main neutral.
So the RCD monitors both of these two. If there is an imbalance, it trips. How much of an imbalance? Well standards here dictate 30mA. Which as you know is three fifths of fuck all. If there is 30mA difference in the balance then it can only be going one place. Through earth and back to the main neutral via the M.E.N. This means there is an earth fault somewhere. Imagen if it is the fridge. As soon as someone comes and grabs the handle they could potentially get an electric shock. But they should not with an RCD. If the fridge is WELL insulated from the ground. Like it has rubber feet and is not touching the floor etc and the RCD has not tripped, it will trip as soon as someone touches it and completes the circuit to ground. How fast? I cant quite remember what the standards dictate. I think its 200ms. Most will trip in something like 23ms. Thats fucking fast. You wont feel anything.
I suspect you already know all I have typed anyway, but I think its good to mention in case anyone is going to replicate your good work.
Peace.
hey man yeah it sucked sooo bad i cried like a beotch over it-
i was at work- left the electric blanket on low- never own one!!!
but i did and the place went a blaze- i was an hour away at work and nothing i coul do about it but work, go home, and see what was left over-
all my music gear and collectibles was the biggest loss-
i lost about 10k in guitars and amps- everything i ever worked for-
but you rebuild and live on -
that kinda shit humbles a man -
so im realy grateful for the experience in the end
thanks for the info! i learned something! you seem to know your electrical !
I had no idea of the RCD's and we do not use them here-
Our breakers are about it- standard wiring is 12 gauge-
it runs 110-120v
up to 30 amps safley but most hmes here o the 15 amp breakers with a few 30's-
i am guilty of replacing all the 15's with 20's!!! im one of those folks for sure lol-
anything over 30 amps here in the states and we swap over to a 220v system.
we use this for dryers and washers, dishwashers, heavy load appliances etc-
you would think the world leaders would sit down and say..ok heres a system that works the best, lets allllll use it! lol
nope- would be to logical lol-
crazy aint it?
lol
you know a little more about electrical then i do from the sounds of it- i'm a novice with bass nutz lol-
i know 120 hurts like hell when it bites, but it usually wont kill anyone- so far ive tested for RF frequencies, and non grounded areas , cant find any-
i think there might opssibly be an RCD type system or RCD built into the AC/DC distribution panel- its very possible cause there built for cars basically-
RV's so they ground out with just a copper wire-
This has my gears turning for sure and I appreciate the time you took to inform me of this kinda thing-
so far its made it almost a solid year without a hitch-
most of my appliances household wise have been swapped out for power consumption saving-
instead of having a huge fridge- well its just me and the wife- i do the cooking, so i opted for a 4cuft mini fridge with freezer that only burns 104watts-
i swapped out my huge water heater and tank for a tank-less propane one- i swapped my stove over to an old propane one and put in a wall furnace as well for heating in the winter-
soon i'll get a large antique wood burning furnace/stove, love those-
almost all my grid power use goes to furnish my grows-
then i have this solar grow as a personal smoke and self sustainable grow-more of an experiment then anything but it doubles as a life support system if i needed it to-
makes life a little less worrisome-
