Wiring 120V to central vacuum outlet

The house I bought a couple of years ago has a central vacuum unit that only is only wired for 24V. Though the unit has the powered rug beater head, the people that had the house built (or reportedly more-specifically, the male of the couple) were too cheap to wire the outlets for 120V. Access to outlets isn't too bad (either unfinished wall behind) or should be easy to run up a wire. How does one wire these outlets? 120V straight to each outlet with a common circuit breaker for all?

Why would you run them all back to a single breaker. Just stub into the nearest outlet. You know you dont need to build 120V into the vacuum outlet - just have a power outlet near the vacuum outlet?

What a weird setup. Our central vac outlets were roughed in with a 120V receptacle either next to them or close by.

You had a builder that was top drawer! Most new builds don't automatically come with a plug beside where the vac canister would hang - despite being code. I had to force my builder to put one in after going through conciliation. Sounds like OP didn't/doesn't have a plug beside the vac canister and original owner rigged something together to make due (which clearly isn't working for OP).

When you say outlets - do you mean your central vac outlet? Or a standard 120v outlet? You should NOT have 120v going to a standard central vac outlet, it's low voltage for safety reasons to turn the main vacuum on and off. The 120v for the accessories such as a power head is usually attached to a simple plug that you is attached to the hose and gets plugged in when used.

The vacuum unit is an Aerus / Electrolux that does have 120VAC in the vacuum outlet as well as 24VDC if configured to run the powered brush. No plug in cord on the hose (I've seen/used those). The hose plugs in with two small pins into the 120VAC tap.

Every central vac I have seen the pins are for the 24vdc to turn vac on and off. 99% it’s against code to have 24vdc and 120ac in the same box.

Sorry if I wasn’t clear but the central vac roughed-in outlets (first floor, second floor) have 120V plugs either right next to the outlet or nearby (actually for the second floor directly opposite the outlet on the hallway wall).

I install my central vac myself and mounted the main vacuum unit itself in the garage. Turned out the best spot also had a 120V plug nearby so getting the power to the unit was dead simple.

Every central vac I’ve seen has low voltage on the pins in the wall outlet opening to turn the vacuum unit on/off. I’ve never heard of the pins carrying 120V and it certainly wouldn’t be to code.

The central vac beater bar has a separate 120V cord that plugs into a standard 120V wall plug.

Central vacs have inlet ports, not outlets! I've seen what OP is talking about in some of the houses I've worked in.

How common is this configuration? Sounds kinda sketchy having 120V in a fixture without a ground.

As Bianco posted above. Modern outlets have the combined 120v for the power bar as well as the switch contacts for the canister motor. perfectly legal and perfectly normal despite all the protestations above.

OP says all he has on the wall is the switch and suction - no power for the power bar. So he needs to replace his wall fixtures with the ones in Biancos post. And run 120v from the nearest point to each outlet.

I have the system similar to the illustrations Bianco13 posted - 24 VDC is on the tube to provide on/off power and 120 VAC is supplied via pins for the power head. It isn't that new (at least a couple of decades) and I've seen these units in home building thrift shops. Aerus was the old Electrolux vacuum cleaner manufacturer (long-ago spin-off of the Electrolux from the appliance company which owns Frigidaire).

See page 9 on this guide. http://www.aerushome.com/Warranty/Manua ... lation.pdf

I am hoping the outlets (or inlets) weren't glued on as removing and replacing the tubing will be a major PITA.

If what you're saying is correct - in that there is 120v at the central vac outlet, then when it was installed it should have been connected then. So the OP has a breaker that's off or similar. I can't see someone going to the trouble of installing a central vac system and leaving out the required power to run the power head or other accessories.

See it.

The person (a nationality known for thriftiness and blunt directness (so it isn't who you think it might be) had the house built acted as his own GC and put everything to tender for the lowest bid. Yes, he had the central vac system installed w/o the power sockets which come in at least two flavours: one that has the 120VAC inputs and wiring, and one that doesn't. I know I have the latter as the 120 VAC pin sockets are missing from my outlets (the 120VAC power inlet for the house is simply turned 180 degrees if not in use). Lot of other head (or other bodily parts) scratching decisions made. He did have a rationale: House has all hard floor surfaces so technically the beater bar would not be necessary, but he didn't take into consideration having to vacuum rugs.
