Frequently Asked Questions

When should electrical planning start on a new build or major remodel?

Ideally during the design and schematic phase, before framing begins. Electrical systems planned early can be properly coordinated with the architecture, lighting control, and other trades. Changes made after walls are closed are more disruptive and expensive to correct.

What's the difference between adding a subpanel and upgrading the main service?

A subpanel adds circuit breaker space for a specific area of the home, such as a garage or addition, but does not increase the home's total amperage. A main service upgrade raises the amount of power coming in from the utility, which is what's needed when the home's total demand exceeds what the existing service can safely carry.

How do I know if my home needs an electrical panel upgrade?

Common signs include breakers that trip frequently, lights that flicker or dim when large appliances run, outlets or panels that feel warm, and a buzzing sound near the panel. An aging panel from a brand no longer considered safe by current standards is also a reason for evaluation. A licensed electrician can inspect the panel and confirm whether an upgrade is actually warranted.

What electrical service size does a large custom home need?

A 200-amp service is the standard baseline for new residential construction, but larger estates with EV charging, pools, workshops, and whole-home automation frequently call for 400-amp service or higher. The right number comes from an actual load calculation based on the home's specific systems, not a rule of thumb.

Will my existing panel support a new EV charger?

It depends on the home's total service size and how much capacity is already committed to other circuits. A Level 2 charger typically needs a dedicated 40 to 60-amp circuit, so a panel already near capacity may need a subpanel or a full service upgrade rather than an added breaker.

Can a generator or battery backup be added to my existing panel?

Yes, with a properly installed transfer switch and load management planning to determine which circuits stay powered during an outage. Regent5 coordinates generator and battery backup integration, including Tesla Powerwall and similar systems, alongside a review of the panel and service capacity.

How is wiring different for a smart home compared to a standard home?

In addition to standard power circuits, a smart home requires structured low-voltage wiring, dedicated circuits for lighting control processors and equipment racks, and coordination on keypad and equipment locations. This is best planned before walls close, since retrofitting after the fact is more disruptive.
