FAQs
Frequently Asked Questions
Homeowners and business owners across Madison, MS ask us about wiring, outdoor lighting, generators, EV chargers, and commercial fans. Here are straightforward answers from H & H Electric Co. LLC. If you do not see your question, give us a call and we will be glad to help.
Can you add outlets or circuits to a finished room without tearing out walls?
Fishing wire through attics, crawlspaces, and wall cavities lets us reach finished rooms with small access points that are easy to patch. Surface raceway offers another clean option for masonry walls or tight spaces.
Can older aluminum or knob and tube wiring be repaired without rewiring the whole house?
In many cases we can. We inspect the condition, replace the weakest runs, and install proper connectors where needed. If the wiring is beyond safe repair, we map out a phased rewiring plan that fits your budget.
What is the difference between low voltage and line voltage outdoor lighting?
Low voltage systems use a transformer to step power down, making them safer and easier to adjust for landscape accents and paths. Line voltage suits bright floodlights and commercial areas. Most properties benefit from a mix of both.
How many fixtures do I need to light my yard?
Fixture count depends on the size of your landscape, the features you want highlighted, and how much security coverage you need. We walk your property at dusk and design a layout that avoids glare and wasted energy.
Can outdoor lighting run on timers or motion sensors?
Photocells, astronomical timers, and motion sensors automate your system so lights turn on at dusk and security zones activate only when needed. Smart controllers also let you adjust lighting scenes from your phone.
What size standby generator does my home need?
Sizing depends on the appliances you want powered and their starting loads, especially air conditioners and well pumps. We run a load calculation and recommend a unit that carries your essentials with comfortable headroom.
Do I need an automatic transfer switch with my generator?
An automatic transfer switch starts your generator and shifts power within seconds, even when you are away. It also prevents dangerous backfeed to utility lines. Manual options cost less but require you to be home.
How often should a standby generator be serviced?
Plan on professional service at least once a year, covering oil, filters, spark plugs, battery tests, and a load test. Homes in humid climates benefit from an inspection just before storm season begins.
Should I choose a natural gas or propane generator?
Natural gas offers a steady supply from the utility line, while propane stores well and works where gas lines do not reach. Available fuel, tank space, and runtime goals will point you toward the better choice.
Can my electrical panel handle an EV charger?
Capacity usually works out, but we confirm with a load calculation first. If it runs tight, load management devices or a panel upgrade let you charge safely without overloading air conditioning, cooking, or laundry circuits.
Do I need a 240 volt circuit for a Level 2 charger?
Level 2 charging requires a dedicated 240 volt circuit, similar to a dryer or range. A standard outlet works in a pinch but adds only a few miles of range for every hour of charging.
Should I choose a plug in or hardwired EV charger?
Plug in units connect to a 240 volt receptacle and can move with you. Hardwired chargers deliver a cleaner finish, often higher output, and suit outdoor installations. We help you match the choice to your vehicle and garage.
How do I know what size and type of commercial fan my space needs?
Ceiling height, floor area, equipment heat, and traffic patterns decide it. Low ceilings suit standard fans, while warehouses and large halls benefit from high volume low speed units. We assess your layout and recommend coverage.
Can commercial fan installation be done without closing my business?
Most work happens during early mornings, evenings, or weekends, and we complete it in sections. Customers and employees experience little or no disruption while the new fans and controls go in.
Do commercial exhaust fans need dedicated circuits?
Most large exhaust fans and variable speed units do. A dedicated circuit prevents nuisance trips, supports correct breaker sizing, and protects the motor from voltage problems, keeping kitchens and workshops ventilated reliably.
