Smart Home Technology

Renrock Engineering would be happy to hear from you to advise you on the latest in Smart Home Technology systems. Whatever your needs may be, no project is too small, we can design and install something for you.

Some recent examples are below:

Smart thermostat installed offering precise control for clients’ heating that allows control away from home too ( with smart phone app).

Combined smoke and carbon monoxide detector that links with other detectors in your system (of the same type). It speaks to alert you of an alarm or when in test function, has a night light function inbuilt and can be checked and tested remotely (with a smart phone app).

Led tape lights that dim from two positions via smart actuators and retractive switches.

Security camera that is accessed via a smart phone and has two way talk facility with alerts straight to the phone.

This shows a typical image you can expect from your camera. Notice the time is shown for a reference, you can set priority activation areas and if no notification is required for a familiar person, no problem you can set that up too. Do you want to view in real time just for that “peace of mind check”, just click on the app and you’ll see your camera(s) view(s).

Domestic Electrical

Here are some Domestic Electrical projects that we have been involved with:

This shows the office sub DB that in turn supplies 2off other outbuilding DB’s. The inside led fire-rated downlighters are controlled by a motion sensor and so to is the outside canopy led lights. 2off non-maintained emergency fire-rated leds were installed, a radial outside socket circuit, a ring socket circuit and thermostatically controlled sockets for intelligent (low power consumption) heaters.

This shows the new DB and containment system that was installed in the house following renovation works downstairs to allow for a new open-plan kitchen/diner area with associated supplies.

The kitchen/diner lighting had led fire-rated downlighters installed. There was led tape lighting installed on the underside of the diner table, the under-side of the worktop and over the splash-back area. The lighting had smart technology installed to them that allowed 2way dimming control. As well as the lighting, there were new supplies installed for ovens , an induction hob, radial socket circuits, a hot tap supply (provision) and also smart tech combined smoke/co detectors were installed throughout the property with a smart security camera too.

This job was a DB change with sub DB added at the origin too for a garden lodge. A new swa supply was installed to the lodge and also a swa supply to the clients’ stores/workshop at the end of their garden (approx 50mts). The whole electrical installation was tested on completion and a domestic EICR was issued.

This was a Domestic EICR that resulted in a DB change. Environmental conditions at the origin (due to the supply being in the clients’ basement) required the DB to be an insulated type. This then had to be installed within a steel enclosure to meet new regulations.

Commercial Electrical

Below shows some recent Commercial Electrical projects:

We had to design, manufacture then install a hydraulic control panel to operate a boom crane. This had remote and local start/stop controls as required by client.

This was a commercial construction site “temporary TT supply that was installed to allow some sockets and lighting to be utilised whilst construction commenced.

This was 1off the control panels we designed, manufactured and installed to allow both cooling water and hydraulic oil circulation for knuckle cranes.

Industrial Electrical

Here are some examples of recent Industrial Electrical projects:

This 400V, 50Hz, 64KVA generator set was used for a standby (back-up) power supply (UPS) and it had problems with it’s output voltage. We conducted onsite fault finding, repairing, cleaning and insulation testing installing new local protection in a new enclosure before returning the set to full service successfully.

This shows a new main hydraulic connection box that replaced the old broken, overpopulated box with poorly terminated cables. We highlighted various faults to our client and we were able to correct them all at the same time as the change occurred.

A new 100A, 3PH/N+E supply was installed for this site and this shows 1off the new distribution boards installed.

Marine Electrical

Below shows some of the recent Marine projects we have enjoyed working on:

This was a new pier that had a 3PH 100A supply installed, an insulated enclosure with the 3PH DB inside. New led brow lighting complete with emergency lights, led floodlighting, socket outlets as per our clients request. Solar nav lighting at both ends of the pier.

This was a stern tube tank level alarm panel we designed, manufactured and installed as per our clients criteria.

These are stainless control and display panels installed to a complete new build for a split twin hull work boat. We designed the full electrical system (3PH, 63A) to accommodate the clients requests, that included the same rated shore supply.

D.C nav light controls, bilge pump with alarms and 3off fire detection controller all installed on a purpose made stainless engraved panel. There were 2off 24Vdc DB’s installed on the vessel.

This shows 2off the battery bank layouts (there was 4off banks totalled) with manual paralleling switch and m.engine electronic control module supplies.

1off the 3PH 400Va.c 50Hz DB’s ( there were 3off totalled 400Va.c DB’s throughout the vessel).

This is the 3PH 400Va.c changeover supply panel that we designed, manufactured and installed. It allows to select between the generator source or shore supply complete with the facility to monitor the source voltage and phase rotation with a manual selector to change it if the rotation is incorrect.

We were asked to conduct major control alteration to the Main Switchboard 3PH 400Va.c to allow a harbour generator to be used for a much larger load as it’s capacity was not being maximised. We also altered 400A 3PH isolators , adjusting main busbar structure to allow 4pole switching, incorporating mechanical and electrical interlocking as necessary.

Shore supply and harbour gen isolators were changed to allow 4 pole isolation. Installed the facility to monitor all phases of the shore supply.

Installed a new row of 3PH 400Va.c distribution, having the facility to operate via shore supply too.

Some of the switch gear that had electrical interlocks installed.
