The short answer
A dedicated circuit in Magnolia or Tomball is a homerun and breaker that belong to one appliance — microwave, freezer, welder, or EV charger. Janezich Electric checks panel space first, then pulls the circuit and labels it. If the panel is full, we say so and quote a subpanel or upgrade.
If the lights blink when the microwave starts, that kitchen is sharing a circuit it should not. Dedicated circuit installation in Magnolia and Tomball means one appliance owns its breaker. Janezich Electric pulls 20- and 30-amp homeruns for homes and shops.
EV chargers, welders, and freezers fail the same way when they ride a lighting run.
What needs its own circuit
Microwaves, freezers, window units, shop compressors, welders, and EV chargers. A lighting circuit was never meant to feed those.
Panel space first
We open the panel and tell you if there is a slot, if a tandem is honest, or if you need a subpanel. Guessing from the hallway is how you buy the wrong Saturday.
Shops and commercial equipment
POS, refrigeration, and office gear share lighting runs until Friday. Dedicated circuits are cheaper than an outage. After-hours is available.
What to send
A photo of the panel and the nameplate on the appliance. We reply with a written proposal for the circuit, the device, and the label. Call 346-236-3512.
Common questions
When do I need a dedicated circuit?
When an appliance should not share a breaker — microwave, freezer, welder, compressor, or EV charger — or when lights dip when it starts.
What if my panel is full?
We quote tandems only when they are honest, or a subpanel / upgrade when they are not.
Is an EV charger a dedicated circuit?
Yes. A Level 2 charger needs its own 240-volt homerun sized to the unit.
Do you add commercial dedicated circuits?
Yes — shops and offices, after 4pm when the floor cannot go dark.
