02 — What You Notice
Signs of a Loose Neutral, and What to Do Right Then
Homeowners describe it in a few ways. Lights brighten in some rooms while others dim, especially when the AC or a hair dryer kicks on. Bulbs burn out well before their time. A television or computer resets for no clear reason. Sometimes a motor, such as a fridge compressor or a fan, hums or runs weakly on the low side.
If you see that pattern, switch off or unplug the electronics you care about most and hold off on running heavy appliances. Then call us. If you smell burning or see smoke at the panel or meter, get everyone out and call 911.
A breaker that trips repeatedly is a different problem, usually tied to a single circuit. When trouble stays in one room, our Portsmouth troubleshooting service is the better starting point.
03 — Process
How a Portsmouth Neutral Repair Visit Runs
Read the light pattern
Which rooms brighten and which dim, and what was running when it happened, point to the loaded half of the panel.
Check at the panel
Readings at the panel help narrow down which connection is involved.
Find the connection
Main neutral lug, neutral bar, and branch neutrals. If the fault is at the drop or on Dominion’s lines, we document it and contact Dominion.
Repair the home side
Loose neutral connections on your side are tightened or replaced, and grounding and bonding are checked.
Recheck and report
The panel is checked again once the neutral is solid, and you hear what we found.
04 — Who Fixes Which Side
Where Dominion’s Side Ends and Yours Begins
Six in ten Portsmouth homes are single-family detached houses, by Census estimates, so most of them have their own service and their own main neutral rather than a feed shared through a building. The split between Dominion’s side and yours falls at your own drop or lateral.
A neutral can come loose on the utility’s lines, at the splice where Dominion’s line meets the cable on your house, inside the meter base, or at the main neutral lug and neutral bar in your panel. Who handles it depends on where it is.
Dominion’s Blue Book says the connection between the service drop and the service entrance cable is made or broken only by the company’s authorized representatives, and that the company furnishes and installs the service drop and the meter. The same document says items the customer installs and owns remain the customer’s “sole responsibility for all future maintenance.” Your panel and the neutral connections inside it fall on your side of that line.
So we check first. If the loose connection is in the panel, we repair it. If our readings point to the service drop or Dominion’s lines, we show you what we found and coordinate with Dominion. If they point to the meter base or the cable on your house, we explain that those parts are customer-owned and what that repair involves.
05 — Panel Repair
Repairing the Neutral Inside the Panel
One wire per terminal
The electrical code Virginia uses gives each neutral its own terminal in the panelboard. Two white wires pinched under one screw is a spot where a branch neutral can work loose, and every circuit sharing that screw feels it.
We tighten or remake loose connections. Breakers and other listed devices that show heat damage or corrosion are replaced rather than repaired.
Aluminum service conductors
Aluminum service conductors are common, and Dominion’s Blue Book notes that aluminum reacts with air and moisture to form an oxide film that acts as an insulator. Its meter base terminal instructions call for each connection to be tightened properly, which is why a warm aluminum neutral connection deserves more than a simple snug.
06 — Bonding
Grounding and Bonding, Checked While the Panel Is Open
Grounding and bonding wires share the panel with the neutral, and after years of changes they sometimes land in the wrong place.
While the neutral is apart, we check that grounding and bonding conductors land where they belong in the main panel, so the repaired neutral carries only neutral current. The Blue Book also keeps the customer’s grounding electrode conductor out of company meter bases. Meter base work falls outside a panel repair visit, so if we see a problem there, we show you what we found.
07 — After the Repair
After the Repair: Checking What the Voltage Swing Reached
Once the neutral is solid, we recheck the panel and look over breakers and connections the swing may have stressed. Anything that needs more than a repair, such as a panel nearing the end of its service life, is included in a separate written estimate. When replacement makes more sense, our panel upgrade page for Portsmouth covers that project.
Appliances and electronics that reset or acted strangely during the swings are worth testing once power is steady.
