Service Overview

What Is a Dedicated Circuit and When Do You Need One?

A dedicated circuit is an electrical circuit that serves only one appliance or device — with its own breaker, its own conductor run, and no shared load from other outlets or fixtures. The NEC requires dedicated circuits for high-draw appliances including electric ranges (50A), electric dryers (30A), dishwashers (20A), HVAC condensers, tankless water heaters, and EV chargers (40A–50A). Sharing these loads on a general-purpose circuit causes nuisance breaker trips, voltage sag that shortens appliance life, and sustained heat in undersized conductors. B&M Electrical sizes every new circuit against the device's nameplate amperage and the NEC continuous-load rule (NEC 210.19 requires conductors rated at 125% of continuous loads), selects the correct conduit fill, and installs matching AFCI or GFCI protection as required by the California Electrical Code for the circuit's specific location — kitchen, bathroom, garage, outdoor, or general living space.

  • Dedicated 120V and 220V circuits for HVAC, ranges, dryers and specialized equipment
  • Level 2 EV charger installation — NEMA 14-50 and hardwired 40A–60A
  • Correctly sized conductors, conduit and breaker capacity for every load
  • Flicker-free power designed for long-term safety and predictable performance
  • Permit pulling, utility coordination and clean inspection pass

What You Get

When Do You Need a Sub-Panel Instead of a Full Panel Upgrade?

A sub-panel is a secondary load center fed from your main panel that distributes power to a specific area — a detached garage, workshop, ADU, pool equipment zone, or remote kitchen. The key advantage over running individual circuits from the main panel is voltage drop: long conductor runs lose voltage proportionally to distance and load, and a correctly sized sub-panel feeder keeps voltage within the NEC-recommended ±5% tolerance at the breakers serving your equipment. Sub-panels are the right solution when you need three or more circuits in one location more than 50–75 feet from your main panel, when you're adding a structure that needs its own disconnect, or when your main panel is full but your service amperage has unused headroom. B&M Electrical calculates the correct feeder conductor size for voltage drop, installs a grounding electrode system at the sub-panel structure, and handles the permit and final inspection.

I had a great experience with this electrical service. The team showed up on time, worked efficiently, and finished the job faster than I expected while still doing everything the right way. The price was very fair compared to other quotes I received, which made the whole experience even better because the quality of work was still top-notch. I also want to give a shout out to Barrett for being professional, knowledgeable, and easy to work with. He made sure everything was taken care of before leaving and you can tell he takes pride in his work. Overall, great service, great price, and I would definitely recommend them to anyone needing electrical work done.

B&M has done a couple jobs for me in the past year, very pleased with the work. Fast, efficient, fair pricing and the work is always really clean. Definitely a returning customer.

Barrett came out and gave me a good price on the work. They replaced my electrical panel and installed a disconnect for my AC unit. Then the next day, had a guy come out to patch up the wall and paint when the stucco dried. He also had the number of an AC technician for me to call to move a thermostat wire. Overall, great work and very communicative throughout the process.

Frequently Asked Questions

New Circuits & Wiring FAQs

Answers to the questions we hear most often from homeowners and business owners across the Antelope Valley.

Do I need a dedicated circuit for my new appliance?

Most high-draw appliances require their own dedicated circuit by code — that includes electric ranges, wall ovens, cooktops, electric dryers, HVAC condensers, tankless water heaters, EV chargers, hot tubs, welders and large garage compressors. Running these off a shared circuit causes breaker trips, voltage drop, premature appliance failure and, in some cases, overheated wiring. We'll verify the nameplate amperage and install the correctly sized conductor and breaker.

How much does a 200-amp panel upgrade cost?

In the Antelope Valley, a straightforward 100A to 200A main panel upgrade typically runs $2,500–$4,500 depending on the panel brand, meter location, whether the service drop or mast needs replacement, and any utility-side coordination. Complex upgrades — detached meter mains, underground service, or panel relocation — are quoted after an on-site walkthrough. We pull the permit, schedule the LADWP or SCE disconnect, and handle the inspection.

Can you install an EV charger at my house?

Yes. We install Level 2 EV chargers (NEMA 14-50 outlet or hardwired 40A–60A units) for Tesla, ChargePoint, JuiceBox, Wallbox, Grizzl-E and every other major brand. We size the circuit against your panel's available capacity, install a dedicated breaker, pull the permit, and coordinate with your utility's EV-rate or rebate program where applicable.

Do you do full home rewiring?

Yes. For older homes with knob-and-tube, ungrounded two-prong outlets, or deteriorated aluminum branch circuits, we plan and execute full or partial rewires. That includes new homeruns in modern copper Romex, grounded three-prong receptacles, GFCI and AFCI protection where required, tamper-resistant outlets, and minimally invasive drywall cuts so patching is fast and clean.

When do I need a sub-panel instead of a bigger main panel?

A sub-panel is the right call when you're adding a detached garage, shop, ADU, pool equipment area, or a remote kitchen or office — basically whenever you need a cluster of new circuits in one location far from the main. A sub-panel shortens your runs, reduces voltage drop, and gives you a convenient disconnect at the new load center. If your main panel is already full but has adequate total amperage, we can also install a feed-through or tandem arrangement to make room.

Will I need a permit?

Yes — new circuits, panel upgrades, sub-panels, EV chargers, and most rewiring work require a permit in Los Angeles County and incorporated cities like Santa Clarita, Palmdale and Lancaster. We handle the permit application, meet the inspector on site, and pass inspection on our first visit. Unpermitted electrical work can create problems during a home sale or insurance claim.

How long does a new circuit installation take?

A single dedicated circuit to a nearby location typically takes 2–4 hours on-site. A longer run through finished walls, a panel-board upgrade, or multi-circuit installs for a kitchen remodel or ADU may take a full day or more. We'll give you a firm timeline in writing before work starts and protect floors, cabinets and finishes throughout the job.
