uh welcome to sb seeker setting vessel seeker we're getting ready to start the dc
wiring and i've forgotten everything that went in but there's 12 volt there's 24 volt
and then i need the amperage off everything and then we're going to lay out the
circuit breakers then maybe somebody like chris pilling will come back in and do the wiring for us
but chris fellows is here today we're inside in the shade because it's hot outside and freaking
what day of the week is like september first week of september we're 20 degrees above normal
summer hasn't quite finished it's the second week of october the second week october thank you
i'm retired i don't have to know these things
so i know there's two build pumps and two mass and a macerator pump and two water pumps underneath
here so you're just gonna make the list of what all it is and then i'll give you the amperage
if i can find it i can't i'll look it up two water pumps 24 volt one macerator pump 12 volts 6.5 amps
so we got our list now and we got to go figure out uh how that comes out in breakers and then the
size of the box so there's our dc box down there and so we're gonna how much have we got that's
just nine but if it's gonna come three inches out it's gonna hit it's gonna hit that what if we put
it on the ceiling like you suggested yeah that's you got 18 inches right there yeah and how wide
oh yeah well yeah i like that better you can make the box even 10 inches yeah this is fine it's
right there next to the cable tray most of the wires are going to come down and go underneath
the pumps and stuff that's in the floor well the other thing is if the box is here you can't come
out of the bottom of the top you have to go to the side uh yeah come out anywhere you want
hey we think we know what we're doing no we don't so here's the way it works these are
din rail mounted breakers and these are called the supplementary breakers they're not the real
breaker which means they're not tested so much and they cost only 10 and 50 cents a piece so i can
afford that and so essentially you get not just a breaker but a switch on each item and we made
up a list and so the engine room's probably the worst you know it's got hydraulic pumps
24 volt 12 volt and so forth the way these work is you got these din rails they mount into
our box that we're going to build and then these things have a little snap clip on the back
so you just hook in one push down and it locks itself in just like a kind of like a breaker and a
panel set it doesn't need the face plate on it to hold it in place and then along the side where you
get power in you can get these things which are a bust and i'm not going to use i'm going to use
this one because i bought it but they make these so that you can cut them to whatever length you
want or you could just use wire along the back here and you feed 12 volts into all this right
and so this is a lug that can go in there too and you can feed in the 12-volt there now we're gonna
have 12 and 24 so part of this is going to be 12 volt and then the rest of it's going to be 24 and
we can just change you know 24 will come in on one side 12 on the other and they'll work toward
each other and there'll be a gap in the middle because we're going to build the box big enough
that it takes more breakers than what we need then the other thing you need is a a common or
a bus bar in here to tie all the negatives to so you know two wires from a pump come up one
goes to its breaker the other one goes to here where it gets all tied together and this this
is kind of weird to me but it doesn't make any difference apparently if you put 12 and 24 volt
negatives all here everything negative goes there power coming in will be 12 and then some 24 for uh
well we got two big hydraulic pumps and then see each of these has its own amperage rating
so there's a 10 amp there's a 5 amp so this is c5 c2 3 and so you can buy these in a variety of
amperage and i think we're going to like this system we looked at building the box out of
wood but i think we're going to go with aluminum because we'll just put a piece of
plastic in there mount that into the box and then put our common bus bar on that because
we don't want the box to be negative i don't think it would hurt if we did but
you know what it really wouldn't hurt if we did because the box is going to get mounted to wood
so what difference does it make we just make the whole box negative yeah okay you don't need that
you put that backing bar in there it would suck up that heat wouldn't do any of that
all right so practice is over this is called an edge to edge joint so the weld just goes
in along here and a big ass copper backing bar make sure that the heat has some place
to go so you don't burn through because our welders set really hot spray mode
yeah so that's beautiful yeah any of the soot all that just wipes away
that cracking is making because your movements are too fast okay
no it's great yeah if you'd slowed down you'd have more crown to the weld and
you could probably just round it over right now right but doing that it's great just do another
pass like that and then we'll round it over it'd be great i'll do it now or should i wait for it's
cool let it cool off the other thing that we didn't do here is we didn't put the backing bar
in so you're gonna have a lot more heat that needs time to go away before you can put another weld on
so
uh
yeah i like these
oh yeah so i think you gotta weld a dog hinge there
didn't look hot no that must be the last one you welded
yeah that is actually yeah yeah okay i did the same thing about five minutes ago
so if you you got to figure out how far down to come with it so it will open up all right yeah
oh that's gonna work fine to weld it in now
look at that that's perfect all right i'm off to home depot get some buckets of glass
do a couple passes you don't do you do like spaghetti you score it a bunch of
times and then yeah you snap it that does not seem as fun as a table saw
well it depends on your definition all right i'll try it i'll try it so these special tools
pull it so like you're yeah like that try that i think that's how you're supposed to use it
oh you mean gouge yeah oh i see that plows a furrow is what you want what it sounds like it's
doing something now it wants to cut easily come out of line yeah i'm sure that squirted enough
you just bend it and snap it okay i like my table saw it may be the operator okay i'm not going to
blame the blade yet did you yeah okay there it goes yeah you're just working from one edge boom
okay
okay so i'm surprised it did that without shattering it we got the magnets but they
don't fit a number six screws so we're trying to drill them out just a little bit
yeah it worked beautiful i tried welding this in these things are just too
thin the the back of the box is 3 16 aluminum and these din rails are just nothing so you
can't get enough heat into the back of the box before the din rail starts to go
you don't know how you use a correct curd the simplest device like that i
oh that's cool so there it is din rails mounted in breakers snap onto that got the bus bar down there
cable connectors on the uh edges of the box where the cables go in and out a little magnet
mounted down there look at that in that just beautiful okay get these things out you just put
a screwdriver in there and you pull that little thing out and it comes right up you don't have
to pull it all the way out we had something that didn't do that this one very cooperative
i actually forgot i did that until like until i did it this morning when i was trying to get it
out i was afraid to break something well you know what when you do it with a screwdriver they work
just great yeah well you can do that just kind of pull it out a little bit just enough to get
them off but yeah it's tighter than what you feel like you ought to be doing yeah sort of delos or
vagabond or anybody like that been through uh around the horn
no they all go through the wall see okay so you got different types of breakers and i bought
c's see that c10 now the 10 is the amperage the c is the breaker type and what does that mean it's
basically how fast it's going to trip out when you go over its rating so how long is like a long time
six seconds a couple seconds yeah couple seconds depends on how much over current you're going and
if you get a d how's that different d is even longer it lets you go over current even longer
before it jumps why would we need a d as opposed to a c or a b well if you've got something like
a motor or transformer or something that's got a really really high inrush current when you first
turn it on it might go over the current rating but only so it's sucking up so much energy at first
it's over the 10 amps right but only for maybe a second or two yeah and if we wanted to trip
really fast you'd do a b curve cool see all that college does pay off doesn't it theoretically yeah
okay ah lovely
okay boxes are done hinged even the acrylic on the front next thing to do is start wiring dc stuff up
so
do
you
