I am looking into installing an EV charger in my condo that taps into the load of my meter. I've gotten three very different opinions on if I have sufficient capacity to install the charger without also adding a 1.2k DCC that allows an EV charger to be installed without impacting peak load. The DCC accomplishes this by temporary turning off the charger if it sees too much power is being drawn.
1. Electrician 1 thinks I can do a full 50 amps without a DCC
2. Electrician 2 thinks I can do 30 amps (24 amp charger) without DCC
3. Electrician 3 thinks I have no safe capacity and I need a DCC no matter what.
My meter is providing 125 amps- and my panel is also rated for 125 amps. Any thoughts on who is correct? I tried adding up the total number of circuits in my panel, but that's way more than 125 so must not be the way to do the math.
In total I have
12 - 15 amp breakers = 180
7- 20 amp breakers =140
1 - 25 amp breaker
1 - 30 amp breaker
1 - 40 amp breaker
Grand Total = 450 amps
Here's also a photo of my panel.
Thanks!
