School and daycare electrical work: scheduling around students

School and daycare electrical work is shaped by two things: the children in the building and the calendar. Many classrooms were wired when the room held a chalkboard and an overhead projector, and today they carry charging carts and a device on every desk. The work to catch up has to fit into summers, long breaks and the hours after the last bus. This guide covers how we plan that work for San Antonio schools, private schools and daycares, what the code asks for in labs and kitchens, and how a summer project stays on schedule.

What does school and daycare electrical work include?

It includes classroom power and technology, lab, shop and cafeteria kitchen circuits, emergency lighting and exit signs, and general repair. For a daycare, it is mostly classroom receptacles and lighting, kitchen circuits and emergency lighting. For a larger school, it adds science labs, career shops and the bid process a district uses.

The common thread is that the people using the building are children. That changes where receptacles go, how a work area is closed off and when the noisy or risky parts of a job are done. It also means the life safety systems, the lights that keep hallways and stairs lit when the power fails, are checked and recorded so the fire marshal finds them in order.

Why do older classrooms need more circuits?

Older buildings were not wired for today's classroom. Projectors, charging carts and devices on every desk add load that the original circuits were never planned to carry. We add circuits where the load has grown, and plan the receptacle locations with the school so cords are not run across the floor.

The signs of an overloaded classroom are familiar to any teacher: a breaker that trips when the charging cart and the projector run together, power strips plugged into power strips, and cords taped across the floor to reach the one receptacle on the far wall. Each of those is a reason to look at the circuit, not just reset the breaker.

Receptacle placement is worth planning with the people who use the room. A charging cart needs a receptacle where the cart is parked, the teacher's desk needs power where the desk sits, and a projector needs power where it is mounted. Getting those locations right the first time keeps cords off the floor, where children trip on them.

Smaller fixes, such as a dead receptacle or a breaker that trips, are handled as electrical repair, and can usually be done after dismissal.

Which code rules apply to school labs, shops and kitchens?

Science labs, career shops and cafeteria kitchens each have their own equipment circuits, with the GFCI protection NEC 210.8(B) requires in the locations it lists. Shop equipment gets disconnects where the code calls for them, so the machine can be turned off at the machine by the person working on it.

Each of these rooms has equipment that is wired from its maker's information. A kitchen range, a dishwasher or a lab station each calls for a particular circuit and connection. A shop with saws and other machines needs each machine fed correctly and disconnected where the code requires it. When a school replaces equipment or adds a room, the circuits are checked against the new equipment before it arrives.

Cafeteria kitchens follow the same practice as any food service kitchen, which our commercial kitchen electrical page explains.

How often do school emergency lights need testing?

NFPA 101 sets a monthly 30 second test and an annual 90 minute test for battery emergency lighting units, with written records of both. Hallways and stairs must stay lit when the power fails, and we test, repair and replace units and keep those records ready for the fire marshal.

The annual test is the one that finds weak batteries, because a unit may light for a moment and still fail before the test ends. Units that fail are repaired or replaced, and the record shows each unit, the date and the result. Exit signs are checked at the same visits.

Our emergency lighting and exit signs page covers the work, and the emergency lighting inspection checklist covers what an inspector looks for.

When can electrical work be done at a school or daycare?

Larger school and daycare electrical work is scheduled for summer and long breaks, and smaller work after dismissal. We order long lead items as soon as the scope is approved, so a summer project does not run into the first week of school, and work areas are closed off wherever children are present.

On a site with children present, our work areas are closed off and no open panel or tool is left unattended. That rule holds for the smallest task and the largest job alike. A panel cover comes off only while someone is standing at it, and it goes back on before the crew steps away.

Daycares often run longer days than schools, so the window after dismissal is shorter or does not exist. Work there is usually planned for times the center is closed, with the director agreeing the dates in advance and the rooms checked and returned to service before children arrive.

How do public school districts hire an electrical contractor?

Public districts usually buy through bids, approved vendor lists and cooperative contracts rather than a single phone call. We bid in writing to the district's scope, and we pull the permit where the work needs one, so the district has the paperwork its purchasing rules require before the work starts.

A written bid to the district's scope means the price answers the question the district asked, item by item, rather than a contractor's own idea of the job. Private schools and daycares usually buy more directly, but the same written scope helps a board or an owner compare bids fairly.

Our guide to hiring a commercial electrical contractor covers what to ask for in a bid, whatever the buying process.

What goes wrong on school electrical projects, and how is it prevented?

Summer projects go wrong when parts arrive late and the work runs into the first week of school. We order long lead items as soon as the scope is approved, and plan the work so each room is finished and safe before the next is opened, instead of opening every room at once.

Working room by room means that if a part is late, only one room waits for it, and every other room is ready for the teachers when they come back. Opening the whole building at once can leave every room half done on the last day of summer.

• Approve the scope early so long lead parts can be ordered.
• Finish and close each room before opening the next.
• Plan receptacle locations with the people who use the room.
• Keep emergency lighting records current for the fire marshal.
• Put recurring testing and repair on a maintenance agreement.

A maintenance agreement puts the testing and the small repairs on a schedule. Buildings with similar needs are covered in our guides to church electrical work, since many churches run schools and children's ministry, and gym and fitness center electrical work.

For everything we do for schools and daycares, see our school electrical contractor page, and for the rest of our scope, commercial electrical services. To plan a summer project or a smaller job, describe the building, the work and when it can be done through our contact page, and the owner will respond the same business day.
