What is a Sub Panel?
A sub panel, or satellite panel, is a secondary electrical panel that branches off your main service panel. It distributes electricity to specific areas or high-powered appliances without overloading the main panel. It's essential for:
- Expanding electrical reach to remote parts of your home (e.g., garages or additions)
- Adding large-load systems like HVACs, hot tubs, or EV chargers
- Separating circuits for workshops, home offices, or rental units
Bolton’s varying landscapes and multi-zoned properties make sub panels especially useful for extending power where it’s needed—without a full service panel replacement.
Signs You Need to Install a Sub Panel in Bolton, MA
Your current system may not show immediate failure but could still be too limited. Look for these signs:
- Frequently tripping breakers, especially in older properties
- Limited breaker space to accommodate new circuits
- Planned home renovations or additions requiring new wiring
- Upgrading to high-demand appliances like ductless mini splits or backup generators
Knowing when to install a sub panel reduces long-term risks and boosts electrical performance.
