How to Save Money When Buying Multi Service Terminal Box

Several factors can affect your cost to replace an electrical panel, including the amperage of the new box.

Please visit our website for more information on this topic.

Panel Relocation

If you need to relocate your electrical panel in addition to replacing it, it will drive up the bill. Relocation typically costs between $1,000 and $3,000 depending on the number of circuits and whether the box serves as a circuit junction. These costs are in addition to the price of a new panel.

Labor

It&#;s generally best to hire a licensed electrician to install electrical panels, so you&#;ll want to factor in labor costs. Hiring an electrician typically costs $50 to $150 per hour, and these installations usually take between four and eight hours to complete.

Age and Condition of Existing Electrical Work

If your existing electrical work is damaged or outdated, your pro will need to update it while replacing your electrical panel, which can increase costs. Just how much the price will increase depends on how much of your existing system needs to be replaced or updated.

Trenching

In some cases, you might need to bury an overhead electrical line when replacing an electrical panel. You&#;ll need an electrician to wire it and an excavator to dig the trench. Trenching usually costs around $6 per linear foot.

Amperage of the New Box

Your box&#;s amperage determines how much power your home can use. Generally, the higher the amperage, the more the box costs.

AMPERAGE COST PER BOX 100

$100 &#; $200

200

$250 &#; $350

400

$450 &#; $650

Wiring connections&#;where wires join an outlet, switch or other wires&#;must be inside an electrical box. Here&#;s why: Connections are the weak link in an electrical system. If they get damaged, loosened or pulled apart, you&#;re left without power, or worse, with a fire. Electrical boxes are simply meant to protect vulnerable connections.

If you have the walls opened up for remodeling or putting on an addition, these three boxes cover about 99 percent of your needs.

Box material

Indoor nonmetallic boxes are typically plastic or fiberglass. Cheap PVC boxes like the one shown at far right work fine, but they can move or distort in wood framing as the studs dry. I prefer to spend the extra 20¢ per box on heavy-duty thermoset plastic or fiberglass boxes. Unlike PVC boxes, they&#;re super strong and maintain their shape.

Box Size

Wires, receptacles and switches need adequate space. Crowded boxes can damage wires, resulting in a fire or shock hazard. You can use the chart below to calculate the required box size. Add up the numbers for the correspond- ing components in the box to find how many cubic inches you&#;ll need. In most cases, I skip the math and just buy the largest volume box available in the style I need. I&#;ve never been frustrated by having a box that was too large.
