Trition T90 shower problems and installations

We have been receiving a lot of calls about the T90 Shower and ongoing issues after a new installation. Some of the problems include melted wiring, faults in the operation of the shower or the unit tripping out the existing fuse board. The problem presents itself as the old wiring that was running the original shower is insufficient to power the new requirements for the Triton T90. In the majority of cases, the wiring will need to be replaced from the fuse board to the electrical shower unit in order to make sure that your new Triton shower will function correctly.

The size of cable that can be used for an electric shower depends on a number of factors which includes, the kilowatt rating of the shower, the method of cable installation, any de-rating factors and the length of circuit. In some cases 6mm² cable will be adequate for a shower rated up to 8kW. For showers above 8kW it may be necessary to install 10mm² cable.

What will happen if the incorrect fuse size is fitted for an electric shower?
If an under-rated fuse is used it will be overloaded and will keep tripping out. If the fuse rating is too large it will not disconnect the supply quick enough under a short circuit fault condition. To avoid these problems the correct size fuse/mcb must be fitted for the kW rating of the unit in accordance with the I.E.E. regulations. Sizes required are:

7kW = 30/32amp mcb.

7.5kW = 32amp mcb

8kW = 40amp mcb

8.5kW = 40amp mcb

9.5kw = 40/45amp mcb

10.5kW = 45/50amp mcb

In order to comply with Part P building regulations a competent installer familiar with the requirements of the current I.E.E regulations must assess the proposed circuit in order to select the correct cable size. We have found that in a lot of cases, the shower installer is not doing this and as a result, malfunctions can occue in the operation of the shower.

Every electrical shower we install fully confirms with the legal requirements for safely wiring up the unit in any home, business or office. In most cases, the existing cabling will be sufficient for a straight forward installation. However, in cases where the wiring needs to be switched, we will be happy to quote a price for the complete shower installation and replacement of existing wiring from the fuse board to your new shower unit.
