Finding the best grasside ev chargers with hardwired connections requires looking at specific electrical ratings. We compared 2 models to help you choose. The Grasside 48A Level 2 Hardwired EV Charger leads this list because its 48A amperage delivers the fastest charging speed available in this group. All selections are based strictly on the specifications published on the product listings. This guide helps you decide which unit matches your home circuit capacity and daily driving needs.
Match your circuit amperage to the charger
Both Grasside options deliver 48A, requiring a dedicated 60-amp circuit. If your home electrical panel supports this capacity, you get maximum Level 2 speed. If you are limited to a 50-amp breaker, this amperage may trip the breaker. Check your panel rating before installing. The 25-foot cable adds reach for most garages.

How to Choose Your Grasside EV Charger
Check Circuit Compatibility
Both models in this guide require a dedicated 60-amp circuit to operate at their full 48A capacity. You must verify your home electrical panel can support this load before installation. If your panel only supports a 50-amp breaker, you may face tripping issues with these high-amperage units. Ensure your electrician confirms the circuit rating matches the charger’s requirements for safe, uninterrupted charging sessions.
Verify Cable Length Needs
The Grasside 48A Level 2 Hardwired EV Charger includes a 25-foot cable, which suits most driveways and garage setups. If your parking spot is further from the installation point, this length may be insufficient. The other 48A model listed does not specify cable length in the provided data. Measure your distance from the charging station to the vehicle port to ensure the included cable reaches without strain.
Confirm Connector Type
Both chargers feature a J1772 connector, which is the standard for nearly all electric vehicles in the US market. You do not need an adapter for most EVs, including Teslas with the included adapter. This universal connector ensures compatibility with your vehicle’s inlet. Verify that your car accepts J1772 plugs before purchasing, as this standard remains the industry norm for Level 2 charging infrastructure.
Assess Intended Use
One model is explicitly intended for home use, optimizing it for garage environments. The other is described as robust for outdoor readiness, suggesting better durability for exposed locations. If you plan to mount the unit in an open driveway, choose the model with weather-resistant build qualities. For indoor garage mounting, the home-specific model may offer a better fit for your space and usage patterns.
Review Model Specifications
The Grasside 48A Level 2 Hardwired EV Charger carries the model number NECS-ACW-11.2-1-US-3028 Button Version. The other unit is the NECS-ACW-11.5-1-US-3028. These specific model numbers help you identify the exact unit in manuals or support forums. Check these identifiers when registering your device or seeking warranty support to ensure you reference the correct hardware version for your needs.
Frequently asked questions
What is the maximum charging speed for Grasside hardwired EV chargers?
The maximum charging speed available is 48 amps. Both models in this guide deliver 48A, which supports rapid Level 2 charging. This high amperage allows you to replenish your vehicle's battery significantly faster than standard 16A or 32A units. It is ideal for drivers who need maximum charging speed.
Do these Grasside chargers come with a cable?
Yes, the Grasside 48A Level 2 Hardwired EV Charger includes a cable. It features a 25-foot cable length, providing ample reach for most parking spots. The other 48A model does not list a specific cable length in its attributes, so you should verify the exact setup for that unit before purchase.
What type of connector do Grasside hardwired chargers use?
Both listed Grasside chargers use a J1772 connector type. This is the standard connector for nearly all electric vehicles in the United States, including hybrids. You can use these units with any EV that accepts the J1772 plug without needing an adapter.
Are these chargers suitable for outdoor installation?
The Grasside 48A Level 2 Hardwired EV Charger is described as having a weather-resistant build quality suitable for outdoor use. It is designed for drivers who value durable outdoor readiness. The second model is intended for home use, likely in a garage, but specific weather ratings are not detailed for that unit.
What is the difference between the two Grasside 48A models?
The primary difference is the model designation and intended focus. The first model, NECS-ACW-11.2-1-US-3028, includes a 25-foot cable and is noted for outdoor readiness. The second model, NECS-ACW-11.5-1-US-3028, is specifically branded for home charging. Both deliver 48A amperage for high-speed Level 2 charging.
Can I use these chargers with a 50-amp circuit?
No, you should not use these chargers with a 50-amp circuit. Both models require a dedicated 60-amp circuit to operate safely at their full 48A capacity. Using a 50-amp breaker may cause the circuit to trip due to the high amperage demand, preventing the charger from functioning correctly.
Do these Grasside chargers support smart scheduling?
Yes, the top-ranked Grasside 48A Level 2 Hardwired EV Charger supports smart scheduling. This feature allows you to set charging times to take advantage of off-peak electricity rates. The second model mentions smart features generally, so specific scheduling capabilities may vary between the two units.
What color are the Grasside hardwired EV chargers?
Both listed Grasside hardwired EV chargers are available in black. This neutral color helps them blend into most garage or exterior wall installations. The specific model numbers indicate they are part of the same product family with consistent aesthetic design.
