Level 2 EV Charger Installation in Myrtle Beach, SC
One fixed price before the work starts, and a real person on the line around the clock.
What size circuit does a Level 2 charger need in Myrtle Beach, SC?
Most homes land on a 40-amp charger fed by a dedicated 50-amp 240V circuit. A 48-amp charger needs a 60-amp circuit, and that is the point where your existing service capacity, not the hardware price, decides the job.
EV charging is a continuous load, which means the circuit gets sized above the charger's draw rather than at it. That is why a 40-amp charger does not sit on a 40-amp breaker. It is also why the difference between a 40-amp and a 48-amp charger is not eight amps of convenience, it is a different conductor size and often a different answer about your panel.
This market splits cleanly in two. Pre-1995 beach and Forestbrook or Socastee housing tends to be capacity-limited. Post-1995 master-planned and golf-community housing was generally built with a 200-amp baseline, which is why EV calls out here are capacity conversations rather than failure conversations.
Amperage Is a Panel Decision, Not a Shopping Decision
Buy the charger first and you have made a decision about your electrical service without knowing what your service can do.
The load calculation is the whole game. It adds up what your panel is already committed to, compares that against the service rating, and reports how much headroom is left for a new continuous load. A panel with 30 amps of usable headroom supports a 24-amp charger comfortably and a 48-amp charger not at all, and no amount of wanting changes that.
There are three honest ways out when the headroom is not there. Drop to a smaller charger, which costs nothing and adds charging hours you will almost certainly never notice overnight. Add a load management device, which shares capacity between the charger and another large circuit so the two never draw at once. Or upgrade the service, which is the real answer for a house that was going to need it anyway.
The order matters. Ask about the first two before anyone quotes you the third.
What Actually Sets Your Amperage
How Level 2 EV Charger Installation in Myrtle Beach, SC Runs
Load calculation on the existing panel
Documented, not eyeballed. This is what determines the largest charger your service supports today and whether load management is on the table.
Time on site: 20–30 minutes
Charger and amperage confirmed
Hardware chosen against the calculation and against what your vehicle can actually accept, so you are not paying for amps nothing will use.
Time on site: same visit
Route planned and permit filed
Shortest practical path from panel to mounting point, then the permit application to the authority that covers your address.
Time on site: before install day
Circuit run and charger mounted
Conductors pulled, disconnect provided where required, charger mounted and terminated, then torqued and labeled.
Time on site: 2–5 hours
Load test and inspection
Tested under real charging load before the electrician leaves, then the inspection scheduled with the permitting authority.
Time on site: same day, inspection follows
When it’s doneA dedicated, permitted, inspected 240V circuit sized to a documented calculation rather than to a guess.
What a Level 2 Circuit Costs Here
USD
- Level 2 charger circuit, panel has capacity$1,100–$3,200per installCircuit, permit and labor. Local listings put a straightforward run to a panel with capacity near the bottom of this range; coastal jobs needing corrosion-resistant outdoor equipment sit above it.
- Service or panel upgrade, when the calculation says so$1,800–$4,800add-onHigher end reflects jobs that also need flood-zone elevation work or utility service-line coordination, both more common near the coast than inland.
- Load management device instead of a service upgrade$400–$1,200alternativeShares capacity between the charger and another large circuit so the two never draw at once. Not always offered unless you ask, and often cheaper than upgrading the service.
- Detached garage or long outdoor run$1,200–$3,500add-onTrenched or overhead run. Sandy coastal soil trenches easily; the cost driver here is corrosion-rated fittings and enclosures at the far end, not the digging.
These are typical ranges for Grand Strand; your written quote is confirmed after the load calculation and before any work begins.
There is no federal charger tax credit to offset these figures. Section 30C expired on June 30, 2026.
32A, 40A or 48A: Which One You Should Actually Buy
Compared onCircuit requiredPanel impactReal-world overnight range
32-amp charger (40-amp circuit)
Best forOlder panels with limited headroom, and anyone whose car sits overnight
- Fits panels that cannot take anything larger without a service upgrade
- Cheapest conductor cost on a long run
- Still fully charges most EVs overnight
- Slower if you routinely need a big top-up during the day
- Can feel undersized if you later add a second EV
40-amp charger (50-amp circuit)
Best forThe default for most homes with 200-amp service
- Matches what most vehicles can actually accept
- Widest hardware selection at this rating
- Usually fits a 200-amp panel without argument
- Still needs a real load calculation on an older or heavily loaded panel
- Overkill for a short commute and a car that charges nightly
48-amp charger (60-amp circuit)
Best forTwo EVs, a long daily drive, or a household that charges in short windows
- Fastest home charging available on a residential service
- Worth it where the car can genuinely accept 48 amps
- Frequently triggers a service upgrade on anything under 200 amps
- Many vehicles cap below 48 amps, so the extra capacity does nothing
- Heavier conductors make a long run noticeably more expensive
If your panel has room and your car can take it, 40 amps is the sensible default. Do not buy a 48-amp charger before the load calculation, because on a 100-amp service it is a service-upgrade decision wearing a hardware label. And if the calculation comes back tight, a 32-amp charger overnight is not a compromise most drivers ever notice.
Permits and inspection for a new 240V circuit
Five authorities cover this market: the City of Myrtle Beach, the City of North Myrtle Beach, the Town of Surfside Beach, the City of Conway, and Horry County for unincorporated areas including Carolina Forest, Socastee, Forestbrook and Little River. A Myrtle Beach mailing address does not put you inside the City of Myrtle Beach.
Outdoor-mounted chargers near the water fail at the terminations
Salt air does not kill a charger, it kills the connections behind it: the disconnect, the enclosure, the outlet if there is one. On oceanfront and lagoon-adjacent properties, corrosion-rated enclosures and a mounting position out of direct spray are worth more over ten years than the difference between two charger brands.
Level 2 EV Charger Installation in Myrtle Beach, SC — questions
The circuit is sized above the charger's continuous draw, not at it. A 32-amp charger takes a 40-amp circuit, a 40-amp charger takes a 50-amp circuit, and a 48-amp charger takes a 60-amp circuit.
Often yes, at a lower amperage or with a load management device sharing capacity between circuits. What decides it is the load calculation against everything the panel already carries, not the panel's age or its label.
Only if the vehicle can accept 48 amps and the panel can supply the 60-amp circuit. Many EVs cap their onboard charger below that, in which case the larger charger and the heavier wire buy nothing at all.
It is a controller that prevents the charger and another large circuit from drawing at the same time, so the total never exceeds your service. It is often cheaper than a panel upgrade and it is worth asking about before anyone quotes you one.
Yes, and which of five authorities issues it depends on the address. Carolina Forest, Socastee, Forestbrook and Little River are unincorporated Horry County even though the mail says Myrtle Beach.
Yes, either by unplugging and moving the connector or by using a charger that supports power sharing across two units. Power sharing splits one circuit between two chargers rather than needing two circuits, which matters a great deal on a panel with limited headroom.
Two to five hours for a straightforward run to a panel with capacity. A detached structure, a long interior run through finished walls, or a service upgrade turns it into a longer job and usually a second visit for the inspection.
