I'm in the middle of a home network upgrade and likely need to also do some electrical upgrades as well.
I have a set of pictures of all the equipment here.
- I have a GE TLM2020 200AMP main panel.
- I have a GE TLM812SCUD MOD2 subpanel.
- I believe this is rated for 125A, but I'm not 100% sure.
- I had a licensed electrician install it a few years ago.
- There are only two circuits in the subpanel (they appear to be 20A each), one for a treadmill in the basement and one for the current network equipment.
*First questions, regarding the breaker in the subpanel:
- The breaker looks like it's either two "slim" breakers in a single slot or one breaker with two switches on it. Either way it's definitely connected to two circuits.
- I looked it up and it appears there are "slimline" breakers and "1-pole" or "2-pole" breakers. 2-pole breakers are for powering a 240V circuit, which is not what I want, so I assume this is 2x "slimline" 1-pole breakers occupying a single slot.
- It has the # "AP120" on it. When I google "GE AP120 Slimline" I get this, which leads mt to believe it's two of those installed in a single slot.
Back to the network & PDU:
- My current equipment is connected to a DLI 16-Outlet/8 Circuit PDU.
- The PDU is has two input circuits, each designed to be hooked up to a separate 15A circuit.
- The input connectors are standard NEMA 5-15.
- The PDU has an onboard 15A fuse for each input circuit.
- The PDU has 8 'output' circuits (two outlets on each).
- Four of the circuits (8 outlets) are powered off input A and four are powered off input B.
- Since I only currently have 1 circuit in the basement, I have both PDU circuits connected to the two outlets on the one circuit. With my current equipment I'm well under the maximum usage.
I have a whole new set of network & server equipment on it's way, including a second PDU (identical to the one described above). I'd like to set up the power properly.
So a couple questions on the electrical wiring & components:
- Most of my home circuits are 20A on Romex 12-2. It appears that's common practice. However, since this PDU is specifically designed to run on 15A circuits, should I stick to setting up 15A circuits with 15A fuses in the box, or should I still install them as 20A circuits? As mentioned above, each PDU has an onboard 15A fuse for each input.
- If I install 15A fuses, I'm assuming I don't need to "downgrade" from Romex 12/2 to Romex 14/3. Sticking with the Romex 12/2 would allow the 15A breakers to be swapped out for 20A breakers in the future without rerunning the cable. Just looking to confirm there's nothing wrong with that.
- Is there any reason to install GFI outlets rather than just standard power outlets for this use-case? I would think not, since there's already a bunch of expensive electronics in the PDUs monitoring the circuits.
So based on that, I think I purchasing the following is everything I need to do complete the project:
- Southwire Romex 12/2WG NMB (250ft)
- 12/2 Plastic Staples
- GE 15A Single Pole Thin Breaker (4x)
- 4 Gang New Work Box
- 4 Gang Wall Plate
- 15A Receptacle (4x)
Does this look good?
I understand that the first impulse is to tell me to have a licensed electrician perform the work. I understand that, respect that, and in the end it may be what I do. I'm got several books on home wiring I'm currently reading and I would like to to do this myself, however if I don't feel comfortable doing it, I'll just have my electrician come out.
So all that being said - any advice or suggestions?
