can someone PLEASE tell me what i need to tell my electrician for L3's?

[frankbitcoin]

I shared with him, verbally, the details of the L3's.  I think I ended up confusing myself.

He was going to have me run TWO units on ONE circuit, a 20amp circuit, 120volt.

That sounded like it made sense to me when reviewing the stats.

Then I called him back because someone online said use a 240volt outlet instead of a 120volt outlet.  so that totally confused me.

can someone tell me what I need to be doing here?  is the 20amp 120volt what I need to be doing to run two units on the same circuit?

I would get 2x 15amp 120volt outlets EACH WITH THEIR OWN DEDICATED CIRCUIT. Or you can always go bigger.

A 20amp 120v will give you 2400 watts but you should only use 80% of that which is 1920watts (I always use 70% which makes it less). You're cutting it close but can be fine. Each L3+ takes up 800 watts as you know.

do you plan on expanding?

Get a 220V 30 Circuit. If you are going to spend the money on electrician, you should have the ability to expand.

You want 220V because it is waaaay more efficient (lowering operating cost).

240 volt. To get 750 watt usage per unit.
120 volt will do 800 watt usage per l3+

Since a 240 volt can do 3840 watt total I would recommend 240 volt 20 amp breaker

120 volt on 20 amps can do half that amount 1920 watt Max. Always run the with 20 percent headroom for full duty cycle so 1536 watt on a 120 volt 20 amp circuit.

But might as well do 240 volt 20 amp at 3840 Max watt capacity * 0.8  = 3072 watt with 20 percent headroom.

I'm not an electrician so my numbers are meant to be general guidelines

Exactly, U just tell the electrician your putting an electric clothers dryer in your bedroom and you need him to drop a new circuit down from the panel, U better hope there is a free breaker slot, or he'll charge u $2k for a new panel

Better if you just show the SPEC's to the electrician so that he can see you need to 220v/110v ( 1500 watts ) ++ but he may not be aware your power supply has a switch 110 or 220

U want 220 volt, but your plug for dryer is not compatible, so you will need to build your own plug that goes from dryer connection to power supply

Best to stay with normal plugs, that way in the future some idiots doesn't plug a hair dryer in your 220v plug,

If U tell the electrician to put in a clothers-dryer plug, its better they're always 30am, most water heaters are 20 amps and that not enough current, generally water-heaters are hard-wired and don't have plugs, but 20 amp plugs do exist, but 30amp plugs are common, you can buy female & male, better to build your own power box, that means you can buy one male 30amp and then get a punch of 30am smaller plugs for your power supply, if your order from CHINA, be sure to ask for the normal 220v plug, as most of the world uses 220v

Really you should be doing this stuff yourself, if you can't do basic wiring why are you doing basic electronic?

Again, all the above stuff is common knowledge for a guy into electronics and shit, u really ought to find a friend who knows this shit, an electrician can cost a lot of money, and require a lot permits with city, and make a lot of problems, if its NOT your house, you shouldn't do anything this shit, as if you burn the house down ( highly likely ) YOU will be held liable.
