Switchboard upgrades in Camp Hill post-war homes: what's actually behind that 1960s panel

Carina is Voltech's home turf. Three out of every four of my switchboard upgrades happen within 5km of my Camp Hill depot, and 80% of those are on post-war brick-and-tile or chamfer-board cottages built between 1945 and 1970.

If you live in one. Stanley, Old Cleveland, Creek, Ferguson, Pemberton, this post is for you.

Carina housing 101

Most of Carina's housing stock is one of three styles:

1. Post-war chamfer-board on stumps, single-storey, hardwood frame, often raised, often built-in underneath at some point.
2. 1950s-60s brick-and-tile lowset, slab on ground, hipped tile roof, simple floor plan.
3. Late 60s-70s brick highset, split-level living up, garage and rumpus down.

Almost every one of these homes was built with single-phase supply, an enamelled steel meter cabinet, and a panel of 6 to 8 ceramic fuses. None of them had safety switches because they didn't exist in domestic use yet.

What we usually find inside

When I take the meter cabinet cover off in a Carina post-war home, the typical findings are:

• TPS (twin-and-earth) PVC cable from the 70s in most of the house. Decent shape, fine to keep.
• VIR (vulcanised india rubber) cotton-sheath cable in the parts of the house that are still original, often the lighting circuits in the roof. The cotton has perished and the rubber has cracked. Replace on sight.
• A 60-year-old earth stake that's been buried under garden mulch, corroded down to nothing, and is doing about 5% of its job.
• One or two extra circuits that have been bolted on over the decades, pool pump, AC compressor, the granny flat, usually back-fed off whatever circuit had a spare slot.
• No surge protection, and Carina is on a hill, so it cops storms.

What an upgrade looks like

A typical Carina post-war switchboard upgrade with Voltech:

1. Free in-home assessment, usually inside 48 hours of your call.
2. Fixed-price quote, emailed within 24 hours of the visit.
3. Pre-day prep. I'll let you know exactly what time the power will be off (usually 9am-11am).
4. Install day. I arrive with the new board pre-built, isolate the supply, swap, terminate, label, test.
5. Surge protection device added to the new board. Highly recommended for Carina's storm exposure.
6. Earth stake replacement, copper, deep, where it should be. Covered in the quote.
7. Old cable check, if I find any black VIR in your roof during the upgrade, I'll show you and quote the fix separately.
8. Form 16 / CES + photos, emailed before I leave the driveway.

Total job: usually 4 to 6 hours, $1,650-$2,400 fitted, lifetime workmanship warranty.

A real Carina job

A few weeks ago I got a call from a couple in Camp Hill Heights. 1968 brick highset, original board, breakers tripping every time the heater came on. Standard call.

When I opened the panel, the bottom-left fuse base was scorched black around the porcelain. Someone had over-fused it at some point, replaced the original fuse wire with a much thicker piece, and it had been quietly arcing inside the cabinet for years. Two more years of that and the meter box would have caught the timber wall behind it.

We isolated the supply that afternoon, cut the old board out, and had a new compliant 8-circuit RCBO board in by 5pm. Total job: $1,990. Total peace of mind: priceless.

If you've got an original Carina post-war board, please don't leave it. Book a free switchboard quote. I'm local, I'm fast, and the visit costs nothing.
