BigBud, plesae help me!
I have a question that I hope you can help with. I have 8 240v lumitek 1000w digi's. The intructions say to wire them with Two hots and a ground. I am going to wire these to a sub panel that I am installing in my room. Problem is that my main panel on the house has all the grounds and nuetrals mounted to the same bus bar.
So, when wiring my sub panel I know that I have to mount the grounds to the ground bar ( I added a second bus bar for grounds) and the neutrals to the neutral bars. So the grounds and the neutrals will be isolated from each other at the sub panel but when they get wired into the main panel they all go to the same ground bar. Is this safe or do I need to dedicate the ground in the sub panel to a ground rod?
Thanks in advance for any help!
Hey mate, I first wanted to ask where you live, and again a diclamer ** i'm not an electrician, and you should check anything I say out by someone that knows thier stuff, as this stuff will kill you dead and blow your bawlz off, stay safe**
So yeah do you live where there's 220 or 240v like say in europe? or are you in the US or canada such as me?
For me being in canada we use 120 primary, and use 220 for the dryers, ovens ect ect. I am thinking your are also on 120v and are getting your lines for 220/240 V.S 120 lines in the breaker box mixed up no?
If you are on 120 then you would see inside your box that you will have 3 connections for the 120. 1 for all your bare copper Earth's to connect to for short curcuits in devices, shielding double duty ect ect, the 120v white wires all connected to a common rail inside the box, and your black wires running into the various breakers.
Now I can tell you how OUR 220/240 power is run inside our boxes here in canada. It's all in the same box as the 120 section, but it is wired much differently. We have out copper comming from our 220 tied into the same bare wire Copper earth point as the 120v, so nothing new there.
Then we have The white wire comming from the 220 line going to the same rail where all the 120v white wires are tied to.
Next we then have the red and black wires going into thier own seperate breakers, in my case each wire getting a 15 amp unit.
So if you think about this, there's your 2 hot's (black and red) each being fed from thier own breaker You then have your neg or common white tied into the bus where all the white's go including the 120v whites, and the earth going to all the other bare wire earth points at thier own bus, which IMHO is the most important connection to make sure you make.
Now again, i'm only assuming your on 120 primary, and am only giving you an example of how our 220/240 is handled inside our boxes.
I'd also like to be clear on which color your calling your "common" and ground, because i've seen alot of people get those mixed up.
So yeah, I'm only giving you info on how were setup, hopeing maby it may give you some insight to the different wiring schemes, and that someone will catch this thread bump, and be able to really help you out.
All the best man, hope someone can help you on your way safely. I just don't know enough to comfortably talk about this stuff when it's not my own life in my hands. Take care man. Cheers, FC.
