Before you buy

Which Spark model is right for my home?

It mostly depends on your electrical panel and your car.

Model Connection Power Breaker
Spark 40A Plug-in (NEMA 14-50) Up to 9.6 kW 50A
Spark 48A Hardwired Up to 11.5 kW 60A
Spark 80A Hardwired Up to 19.2 kW 100A

The 48A suits most homes and most EVs. Choose the 80A only if your car can accept more than 11.5 kW and your panel has room for a 100A circuit. Choose the 40A if you already have a suitable 240V outlet in place.

Should I get the plug-in or the hardwired model?

The plug-in 40A is easy to unplug and move if you already have a proper 240V outlet. Hardwired models (48A, 80A) deliver more power and remove the outlet as a possible point of failure, which is why many electricians prefer them for daily charging.

Do I need an electrician to install it?

Spark 40A plug-in: if you already have a NEMA 14-50 outlet on a dedicated 50A, 240V circuit that was installed by a licensed electrician, you can mount the charger and plug it in yourself. If the outlet is old, worn or you're not sure how it was installed, have an electrician check it first.

Spark 48A and 80A hardwired: these must be installed by a licensed electrician, following your local electrical and building codes.

Improper installation can be a safety hazard and may void your warranty.

Does my electrical panel have enough capacity?

Ask your electrician to do a load calculation. If your panel can't support a full-size circuit, the charger can still be installed on a smaller breaker. You then set a lower charging current in the Spark app to match:

Breaker Max charge current (set in app) Copper wire
100A 80A 3 AWG
60A 48A 6 AWG
50A 40A 8 AWG
40A 32A 8 AWG
30A 24A 10 AWG
25A 20A 10 AWG
20A 16A 12 AWG
15A 10A 14 AWG
10A 6A 16 AWG
Do I need a permit?

Most areas require a permit for a new 240V circuit. Your electrician will know the local rules. Unpermitted work can cause problems with insurance claims and home inspections.

Are there rebates for home EV chargers?

Many utilities, provinces and states offer rebates for Level 2 chargers and installation. See our rebates and grants page to find programs in your area. Some programs need pre-approval or an approved product list, so check before you buy. Contact us if you need product documents for a rebate application.

Electrical requirements

What breaker and wire size do I need?

Each charger needs its own dedicated 208 to 240V circuit with a two-pole breaker. Use the table below, and confirm sizes with your electrician and local code. The circuit must be rated for 125% of the charger's maximum load.

Breaker Max charge current (set in app) Copper wire
100A 80A 3 AWG
60A 48A 6 AWG
50A 40A 8 AWG
40A 32A 8 AWG
30A 24A 10 AWG
25A 20A 10 AWG
20A 16A 12 AWG
15A 10A 14 AWG
10A 6A 16 AWG
Which outlet does the Spark 40A plug-in use?

The 40A model plugs into a NEMA 14-50 outlet on a dedicated 50A, 240V circuit, properly installed and grounded. Use a heavy-duty, industrial-grade receptacle. Low-cost outlets are a common cause of overheating with EV chargers, because charging draws high current for hours.

Never modify the plug, and never use an extension cord or adapter.

Do I need a GFCI breaker?

For residential installs, the Spark manual calls for a dedicated, non-GFCI two-pole breaker. The charger has its own built-in ground-fault protection. Some local codes require GFCI protection on 240V outlets in garages or outdoors. If your electrician must use one and it trips during charging, contact our support team.

Can I use aluminum wire?

No. Use copper conductors only, sized for your circuit and the length of the wire run.

Does it work on 208V?

Yes. Spark works on 208 to 240V. On 208V, which is common in apartment and commercial buildings, charging power is about 13% lower than on 240V at the same current.

Can I put two chargers on one circuit?

No. Each charger needs its own dedicated breaker. Do not share the circuit with other appliances or equipment.

How far can the charger be from my panel?

There's no fixed limit, but longer runs may need thicker wire to prevent voltage drop. Your electrician will size it. For hardwired installs, the flexible conduit (supply whip) from the building wiring to the charger can be no longer than 6 ft (1.8 m).

Mounting

Where should I mount the charger?
  • Close enough for the 24.6 ft (7.5 m) cable to reach your car's charging port without stretching
  • Away from lawnmowers, snowplows and heavy traffic that could hit the charger or cable
  • Within strong 2.4 GHz Wi-Fi range, so the Spark app can schedule off-peak charging, track your costs and keep the charger updated
  • For the 40A plug-in, close enough to the outlet that the power cord hangs naturally
How high should I mount it?

Mount it so the bottom of the charger is 32 to 48 inches (81 to 122 cm) above the finished floor, and the power cord does not touch the ground.

Can I mount it on drywall or stucco?

Not on its own. Fasten the mounting plate into a wall stud, or into solid concrete or brick. Use at least one screw in each of the three rows of holes, and keep the large pass-through hole at the bottom.

Can I install it outdoors?

Yes. The charger is IP66 rated, so it is protected against dust and strong water jets, and it works from -30°C to +50°C (-22°F to 122°F). Avoid spots where water pools or where it could be hit.

Is there an installation video?

Yes. Watch how to mount and install your Spark charger:

Hardwired models must still be wired by a licensed electrician.

What tools does the installer need?
  • Tape measure, pencil and spirit level
  • Drill with bits for the wall material
  • Phillips PH2 screwdriver and 2.5 mm hex key
  • Torque driver (0 to 4 Nm). Terminals are torqued to 2.0 Nm by hand, no power tools
  • Wire stripper, hammer (for the knockout), voltage tester and multimeter
  • Conduit and a gland sized for the knockout
How do I install the holster?

Mount the metal cable holder first using the bottom hole only. Slide the holster over it and screw it to the wall through the top hole and two bottom holes. Wrap the cable over the holder. Remove the rubber cap from the connector before docking it, or it won't fit.

What do I do right after installation?
  1. Turn the breaker on. The lights flash blue, then turn solid blue when ready.
  2. Download the Spark app and add your charger.
  3. Set the maximum charging current in the app to match your breaker. This step is important for safety.

Commercial installations

What are the electrical requirements for the commercial charger? Commercial
  • Dedicated 240V circuit for each unit, never shared
  • 48A model: minimum 60A breaker, typically #6 AWG copper
  • 80A model: minimum 100A breaker, typically #3 AWG copper
  • Dedicated copper ground to the building's main ground
  • GFCI breakers where your local code requires them
Can it be pedestal-mounted? Commercial

Yes. It can be mounted on a wall or a pedestal. Install the pedestal first, following its manufacturer's instructions. Keep 6 in (15 cm) of clearance on the sides and 24 in (61 cm) in front.

What mounting height meets ADA accessibility? Commercial

For ADA-accessible spaces, mount the charger so its bottom sits 27.6 to 33.5 in (700 to 850 mm) above the finished floor.

Should the wiring come in from the bottom or the back? Commercial

Bottom entry suits surface-run conduit and pedestals. Rear entry suits conduit coming flush out of the wall. Remove only one knockout. Removing both breaks the weatherproof rating.

What Wi-Fi does the site need? Commercial

A 2.4 GHz (802.11 b/g/n) router or access point with WPA2 security, within about 50 ft (15 m) of each charger. Signal must be stronger than -60 dBm for stable operation.

How do I connect the charger to a CMS? Commercial
  1. Confirm the charger lights are solid blue.
  2. Download the Spark installer app and follow its steps to connect the charger to the site Wi-Fi and your CMS.
  3. The default CMS is ChargeLab. To use another OCPP 1.6 provider, have the OCPP server URL from that provider ready.
  4. The charger reboots, and the lights turn solid white once it's connected.
The lights blink red right after power-up. What's wrong? Installer

This usually means a loose input terminal, a missing ground, or supply voltage outside 220 to 240V. Turn off the breaker and check the terminations and ground.

The breaker trips as soon as I power the charger. Installer

If the breaker trips before any car is charging, the cause is almost always the wiring, not the breaker size. Turn off the power and have the electrician recheck every terminal connection (torqued to 2.0 Nm) and the ground.

The breaker trips once a car starts charging. Installer

If it only trips during charging, or after charging for a while, the breaker is usually too small for the current the charger is drawing. Check that the breaker matches the charger (60A for 48A units, 100A for 80A units), or lower the maximum current in the app to match the breaker that's installed.

The lights stay blue after I entered the Wi-Fi details. Installer
  • The charger may be too far from the router. The signal should be stronger than -60 dBm.
  • The Wi-Fi password may be wrong. Test it by joining the same network on your phone, then try again.
Can I choose whether chargers keep charging when the network is offline? Commercial

Yes. Chargers can be set to either keep allowing charging or stop charging during a network outage. Email our team at info@soneilspark.com with your site details and the setting you want, and we'll set it up for you.
