The Outlet: August 18, 2026
Hi there,
A new industry profile puts numbers on bad plans, box-fill questions are catching up to push-in splices, and 2026 NEC labels carry more arc-flash detail.
🔦 Fun Fact
For box-fill calculations, a pigtail that begins and ends entirely inside the box generally does not add a conductor allowance. Conductors that enter the box and are spliced or terminated do count, so neat-looking work can still exceed the permitted volume.
😆 Laugh of the Day
Why did the electrician stop adding conductors?
The box had reached full capacity.
📋 Bad Plans Are Still the Rule, Not the Exception
ELECTRICAL CONTRACTOR's 2026 industry profile found that 83% of respondents received incorrect plans or specifications in 2025, while 78% received incomplete ones. Contractors also reported making brand decisions 67% of the time, which shows how often field and purchasing judgment fills a design gap. Treat unclear documents as a pricing and coordination risk before the bid becomes a change-order fight.
📦 Push-In Splices Put Fresh Pressure on Box Fill
Current box-fill rules account for conductors, clamps, equipment, and terminal blocks, but an NEC expert argues that today's larger push-in splice devices can consume meaningful space without a separate allowance. That is a proposal for future clarification, not a new rule. The field lesson is immediate: do the required calculation, then make sure the selected box also leaves practical room for the device and splices.
⚠️ 2026 NEC Arc-Flash Labels Carry More Useful Detail
Revisions to NEC 110.16 expand where arc-flash markings apply and call for information such as nominal voltage, the arc-flash boundary, incident energy or required PPE, and the assessment date. Adoption will still happen state by state, and labels do not replace lockout/tagout, maintenance, training, or a risk assessment. Shops can prepare by reviewing label workflows with engineers, owners, and safety teams before a project reaches commissioning.
Measure the box, mark the hazard, and price the ambiguity.
