ok i only have 2 more spots for breakers so its either 1 220 or two 110 circuits, both would be 30 amps, what one would you suggest?
even if you could the circuit would be completely maxed out.
if your ballast have the adapter inside to switch to 220 with just a simple cord then yes you can run them at 220, but if they are regular multi-tap ballast then i have found no way possible to get 220 out of a single phase panel.
(the ballast needs a 220 leg an a neutral an there is no such thing as a 220 leg in single phase setup. (you have 2 - 110 legs , but not one single 220)
You are going to need some kind of microcontroller, or computer with RS232 to interface the card reader. The idea is, you scan your card - the controller reads the serial signal and decides if your card is correct or not - if card passes then you release the mag lock on the door. You prolly need a relay to controll the mag lock as well. An Arduino may be a good place to start, but I dont know if the protocol that RFID unit uses is known or not.I just got a magnetic lock with a RFID reader, but im not sure how to wire it.

can anyone help?
I have a couple of magnetic ballast from sun light supply. i want to convert them the from 120v to 240v. Can anyone show me how? By the way i already called customer support and the told me that all i had to do is open the the ballast and switch one wire. And then go buy the 240v power cord.
yea they do make a single pole 30 amp breaker, i had one in my hand the other day at lowes... I plan on only running 2 1000 watt lights in the beginning but i would like to have the extra space to expand when my first grow is done... but i think i will just go with 2 20 amp breakers if 10 guage wire wont fit in the outlet boxes
can I run 4, 250w hps bulbs off a single 1000w ballast?
Thanks. My ballasts have a 220v cord. QuantumWhat about a 220v step up transformer in the outlet?
Question:::
I am trying to have a Subpanel...
I am thinking about tapping into a breaker that is on a GFI and its own breaker... 15 Amps....
How could I tap into the outlet?
What are some of the options that let you go big with out pulling such a big power load?
