Site Readiness
A step-by-step checklist for operators preparing a location to host a second ASIC miner rated at 0.05 TH/s or higher.
Before you purchase a second mining unit, your site needs to pass several checks that distributor spec sheets do not cover. This page outlines what Panel Hemlockpath evaluates during a site readiness review — and what you can inspect yourself beforehand.
Electrical Readiness
Breaker capacity. Identify the dedicated circuit for your existing miner. A 30A/220V breaker supports roughly 6,600W continuous. Subtract your first unit’s measured draw (not rated draw) and the remaining headroom is your budget for unit two.
Wiring gauge. Korean residential wiring for 30A circuits is typically 4mm² copper. If your circuit shares a conduit with other loads (lighting, HVAC), sustained mining draw may cause voltage drop that reduces ASIC efficiency. We measure voltage at the outlet under load during our power assessment.
Inrush current. PSUs draw 20–40% more power during the first three seconds of startup. Two units restarting simultaneously after a power blip can trip a breaker that handles steady-state load without issue.
Thermal Readiness
Intake air temperature. Measure the air entering your miner’s fan after 30 minutes of operation. If it exceeds 35°C, adding a second unit will push both into thermal throttling territory during summer months.
Exhaust path. Hot air must leave the room without recirculating into any intake. Basements and garages often trap heat near the ceiling. A smoke pencil test (or incense stick) reveals airflow patterns in two minutes.
Shelf and rack spacing. ASICs need minimum clearance on intake and exhaust sides — typically 15–20cm. Stacking units without side clearance creates hot spots we detect with thermal imaging.
Physical and Legal Readiness
Floor load. A fully loaded mining shelf with two ASICs, PSUs, and network gear weighs 25–35 kg. Confirm shelving is rated for the load and anchored if earthquake safety is a concern.
Lease and insurance. Light-commercial and residential leases in Korea may restrict high-draw equipment. Verify your agreement before purchasing hardware you cannot legally operate at the site.
Noise exposure. Two ASICs at 75 dB each do not simply add to 150 dB — but perceived noise increases noticeably. If your mining area shares a wall with living space or neighbours, plan acoustic baffling or relocation before installation day.
Self-Assessment Checklist
Use this checklist before booking a consultation:
- I know my dedicated circuit amperage and measured power draw of unit one
- I have measured intake air temperature after 30 minutes of operation
- I have confirmed exhaust air leaves the room without recirculation
- My lease or property agreement permits additional high-draw equipment
- I have budget for potential electrical or ventilation upgrades if recommended
If you checked fewer than three items, a Fleet Expansion Consultation will save time and prevent costly hardware mismatches.
