Experienced Electrician here, ask me anything

I have 10kw but actually I want half on and half off at a time. And it's 240v not 120. And I should be ok with just two contactors at 240v.

Yes?

No?

I won't have the equipment needed to cool 10kw running at the same time until later.

And I had more questions in there that weren't touched on at all like the minimum wire guages and relays to flop bulbs. If anyone else has any info on those I'd appreciate it.

Thanks for trying though.

Hay bricktown73.... i got some questions for ya, i only do basic common sence wireing, lol, all i'm capable of..... i have no prob spending the bucks and prefer to do things right the first time......

Q1- How far can i run a 30amp mainline (from garage to house) i want to split the usage, like how long can the full cable length be and still work for say 2X600w hps safley?

Q2 - is there any real benefit to using a 240 plug setup that converts down to multiple 110? and how long of a run can the 240v cable be too...lol...err...220...ah fuk...he he he

Q3 - Will a backup battery thing like for computers work for lights? can't find that answere anyware....

I have done alot of electrical work, but just began working on many different 220v installations.

The digital ballasts they are using require to only use 2 hots and a ground, no neutral.
So I've run 3 phase into a subpanel and run only 2 hots and a ground to a 220v receptacle.

In between the subpanel and receptacle there are 2 Normally Closed solid state relays. Using a 5 volt trigger to switch the the relays on/off.

I've wired one relay for each 110v leg and wired the trigger in series with the 2 relays.

The issue is, the relays will energize the receptacle but will not de-energize.

How can the electricity travel to the outlet, is it back feeding somehow through the ground.

A simple wiring diagram would be awesome. I hear this is a very simple and standard set up, I must be missing something obvious.
I hope you can help me out. Thank You.

I have a question, CEC related (canada).
Regarding surface mounting cables / raceways. I'm looking at table 19 (cec). Has anyone done surface mount wiring in their indoor garden?
What type of cable did you choose, and what were your options?
What were the deciding factors (code/safety/convenience wise)?

I'm a little unsure about the terms exposed to "damp" and "wet" locations, which would an indoor garden fall under - what's the criteria for wet, and for damp?
Also, the term exposed to "mechanical damage", I'm unsure about.

Here's parts of the reasons why. NMD90 is listed under the "For exposed wiring in dry or damp locations" column. NMD90 is also listed under the "For exposed wiring in dry locations where not exposed to mechanical damage" column.
AC90 is listed under the "For exposed wiring in dry locations only" column (and it's the only thing listed in that category, too).
I can't find RC90 cable listed anywhere (haven't called supply store yet) to compare price to AC90.

Thanks for any help.

Got answers for some of this. Just wanted to ask first, while I researched.
