Panels and capacity
200A & 400A electrical service in Houston
If your panel is full, damaged, outdated, or unable to support new equipment, E.S.H. looks at the panel, service, planned loads, and distribution together—not just the breaker box.
What we work on
Electrical service focused on the real problem.
Call E.S.H. and tell us what you are seeing, adding, or trying to power. We will help you determine the right next step.

Before you call
A few questions help us get to the right answer.
- 01
Is the panel damaged, outdated, full, or simply out of capacity?
- 02
Would a subpanel solve the distribution need without changing the service?
- 03
What new equipment, addition, generator, or property use is driving demand?
- 04
Will the work involve utility, permit, or inspection coordination?
What to expect
A clear path from the first call to the work.
Check the panel and service
E.S.H. checks service size, equipment condition, breaker space, and how power is distributed.
Choose the right solution
We determine whether the job needs panel work, a subpanel, a service change, or a more targeted repair.
Service questions
Helpful answers before you call.
Does a full electrical panel always require a service upgrade?
Not necessarily. A panel can be out of breaker spaces without the entire property being out of electrical capacity. The existing service, calculated demand, planned loads, and condition of the equipment all matter.
When might a Houston property need 400A service?
400A service can make sense for larger homes, multiple HVAC systems, major additions, workshops, commercial equipment, or several high-demand loads. The right size comes from the property’s actual electrical demand.
What should I send before calling about a panel project?
Send the property location, clear photos of the panel and service equipment, the main breaker rating if visible, a description of the problem, and a list of the equipment or additions you want to support.
